Installing a rapid roll door correctly is not only a matter of fastening a frame to an opening. The installer must verify the delivered components, assemble and anchor the door squarely, fit the drive and encoder correctly, protect and ground the electrical system, align the safety devices, set the travel limits, and test every operating mode before handover.
This manuel d'installation de porte à grande vitesse explains the complete process for the SEPPES PVC/fabric high speed rolling door configuration shown in our industrial door user manual. It is intended as a practical reference for trained installers, project engineers, contractors, and facility maintenance teams.
Important safety notice: High speed doors are powered industrial equipment. Installation, electrical work, commissioning, maintenance, and repairs must be performed by qualified and trained personnel. A qualified electrician must complete electrical work in accordance with the supplied wiring diagram and applicable local regulations. The approved project drawing and model-specific manual supplied with the door always take priority over this general guide.
High Speed Door Installation at a Glance
Use this manuel d'installation de porte à grande vitesse in the following sequence:
- Isolate the work area and confirm the approved installation drawing.
- Inspect the shipment and identify every component.
- Check the opening, supporting structure, clearances, motor side, and electrical supply.
- Assemble the header and side guides on a flat, protected surface.
- Install the motor, reducer connection, and absolute encoder.
- Route and secure the motor and encoder cables.
- Raise, align, and anchor the door assembly to the supporting structure.
- Install the control box, grounding, safety sensors, and activation devices.
- Confirm the operating direction and set the opening and closing limits.
- Test the emergency stop, safety devices, activation controls, and repeated cycles.
- Fit all covers, document the settings, and train the operator.
Do not energize the door simply because the mechanical assembly appears complete. The door is ready for service only after the safety devices and limits have been tested and the installation has passed a documented handover inspection.
1. Confirm That This Manual Matches Your Door
This guide covers the general installation of a SEPPES flexible-curtain high speed rolling door with:
- A header or door box containing the curtain and roller
- Two side guide rails with sealing brushes
- A side-mounted motor and reducer
- An absolute encoder
- An electrical control box
- Capteurs de sécurité photovoltaïques
- Project-specific activation devices, such as push buttons, radar, a loop detector, a pull cord, or remote control
Motor position may be left-hand or right-hand when viewed from the installation side. Confirm the ordered motor side before assembly. A high speed spiral door, insulated freezer door, stacking door, zipper door, or other special configuration may use a different structure and installation procedure. Request the correct model-specific drawing if the supplied components do not match the arrangement described here.
2. Safety Requirements Before Installation
Set up an exclusion zone around the doorway before unpacking or assembling the door. Keep workers, vehicles, children, animals, combustible materials, and unrelated equipment away from the installation area.
Follow these requirements throughout the work:
- Only qualified personnel may install, commission, maintain, or repair the door.
- Turn off and isolate the main power supply before mechanical or electrical work.
- Before wiring, keep the power disconnected for more than 10 minutes and wait until the controller board indicator has gone out.
- Never work with wet hands. Use appropriate insulated personal protective equipment for electrical work.
- Do not stand, walk, or place tools under the curtain or door assembly during installation, testing, opening, or closing.
- Do not allow anyone to pass through the opening while the curtain is moving.
- Keep the floor and the entire curtain travel area clear.
- Do not modify the controller program, safety circuit, door configuration, or supplied components without authorization.
- Do not dismantle the controller or replace parts without approval from SEPPES or an authorized service provider.
The installation team should also follow the site risk assessment, lifting plan, lockout/tagout procedure, and applicable local electrical and building requirements.
For projects in the United States, installers and employers should also review OSHA’s official Control of Hazardous Energy (Lockout/Tagout) requirements. Other countries and regions may impose different or additional rules.
3. Delivery Inspection and Parts Checklist
Each industrial door is inspected before shipment, but transport damage or missing packages should be identified before installation begins. Compare the delivery with the packing list and approved order.
The standard shipment described in the SEPPES manual includes:
| Component | What to inspect |
|---|---|
| Door header/box with curtain | Dents, scratches, curtain damage, roller or shaft damage |
| Left and right guide rails | Straightness, sealing brushes, fixing holes, cable-routing slots |
| Motor and motor cover | Correct motor side, connector and cable condition, visible damage |
| Electrical control system | Correct supply specification, enclosure and buttons undamaged |
| Hardware/accessory box | Fixing screws, motor fixing bracket, rubber pad, shaft pin, angle brackets and other supplied hardware |
| Photoelectric safety sensor set | Transmitter, receiver/reflector, cables, brackets and fixings |
| Optional controls | Radar, loop detector, pull cord, remote control, airbag/safety edge, interlock or other ordered accessories |
Do not discard the motor-shaft pin or small pads as packing material. Separate and label the hardware before assembly. If the order is incomplete, the motor side is incorrect, or any critical part is damaged, stop and contact the supplier before drilling or energizing the door.
4. Site and Opening Checks
The approved drawing should define the opening size, headroom, side room, motor position, control-box position, fixing points, and required electrical supply. Recheck these conditions on site because an accurate door cannot compensate for an unsuitable or out-of-square opening.
Before assembly, confirm:
- The clear opening width and height match the approved drawing.
- The supporting wall or steel frame is suitable for the specified anchors and operating loads.
- The lintel, floor, and fixing surfaces are complete and free of loose material.
- There is enough headroom for the header, motor, covers, and service access.
- There is enough side room on the selected motor side.
- The floor and surrounding wall are sufficiently level and plumb for alignment.
- Pipes, cable trays, lights, sprinklers, conveyors, and other equipment do not conflict with the door.
- The controller location is visible, accessible, and protected from traffic and water.
- The actual power supply matches the door nameplate and project electrical drawing.
- The safety-sensor line is clear and the activation devices suit the traffic route.
Do not choose anchors only by habit. Anchor type, size, quantity, and embedment depend on the supporting material and the approved project design.
5. Tools and Equipment
The SEPPES user manual lists 12, 13, 14, and 17 mm wrenches, a set of Allen keys, and a drill set for the basic assembly. The installer will normally also need suitable site measuring and access equipment.
Prepare:
- 12, 13, 14, and 17 mm wrenches or sockets
- Allen key set
- Electric drill and bits suitable for the supporting material
- Tape measure, square, spirit or laser level, and plumb-checking tools
- Approved anchors and fixing tools specified for the project
- Suitable lifting and access equipment
- Cable-management and electrical test equipment
- Lockout/tagout devices and required personal protective equipment
Use only undamaged, correctly rated equipment. Protect the painted frame and curtain from the floor, sharp edges, drilling swarf, and welding debris.
6. Step-by-Step High Speed Door Installation Manual
Step 1: Prepare a Flat Assembly Area
Find a clean, flat area large enough for the complete door frame. Lay cardboard, protective film, or another non-abrasive layer on the floor to prevent scratches.
Place the header and guide rails in the orientation shown in the supplied drawing. The SEPPES manual recommends laying the header and tracks face down/reversed on the floor to make the initial connection easier. Confirm the motor side before fastening anything.
Step 2: Connect the Side Guides to the Header
Align the corresponding fixing holes in the left and right guide rails with the holes in the header box. Insert the supplied screws, engage all fasteners first, and then tighten them evenly with the correct wrench.
Check that:
- The left and right guides are on the correct sides.
- The guide entrances align with the curtain path.
- The guide rails are not twisted.
- The header-to-guide joints are fully seated.
- All connection screws are tight and no cable is trapped.
At this stage, the three main parts should form a rigid U-shaped assembly.
Step 3: Assemble the Motor Fixing Bracket
Locate the motor fixing bracket/base in the hardware accessory box. Attach it to the motor with the four supplied screws as shown in the model-specific manual.
Do not lift or carry the motor by its cables. Keep the motor connector, brake cable, encoder cable, and shaft interface clean and protected.
Step 4: Connect the Motor to the Door Shaft
The SEPPES manual shows a retaining pin taped to the motor shaft for transport. Remove the tape, keep the pin for installation, and position the supplied rubber pad beneath the motor assembly.
Align the reducer with the door shaft and slide it into position without hammering or forcing the parts. The door shaft must enter more than half the depth of the reducer connection. Fit the retaining hardware and tighten the lower fixing screws.
Before continuing, confirm that:
- The motor is supported by the correct bracket and pad.
- The motor and door shaft are aligned.
- The shaft engagement is more than half the reducer depth.
- The retaining pin and fixing screws are installed.
- No cable is stretched, pinched, or routed across a moving part.
Step 5: Install the Absolute Encoder
The travel-control system uses an external absolute encoder. Insert the encoder induction magnet base into the reducer and ensure it is close to the reducer end face. Fasten the encoder securely to the reducer using the supplied screws, then insert and tighten the aviation plug.
Incorrect magnet position, a loose plug, damaged wiring, or a damaged encoder can produce an encoder fault or prevent accurate travel-limit setting. Do not strike the encoder or pull the cable during installation.
Step 6: Route the Motor and Encoder Cables
Pass the motor wires through the first round hole in the guide rail, route them inside the rail, and bring them out through the second round hole, following the arrangement shown in the supplied manual.
Place the wires fully inside the internal cable-routing slot. Secure any excess cable so it cannot touch the curtain, roller, shaft, guide path, or fixing points. Protect the cable at every metal opening and maintain the required separation between power and signal wiring.
Step 7: Fit the Header Angle Brackets
Install the supplied fixing angle brackets at the top of the header. The SEPPES manual shows brackets at both ends and, where provided, at the middle of the header.
Engage the fasteners, check the bracket orientation, and tighten them securely. These brackets form part of the connection between the header and the supporting structure; do not omit them or replace them with unapproved hardware.
Step 8: Raise, Position, and Anchor the Door
Raise the assembled door using the approved site method and suitable equipment. Follow the project lifting plan and keep everyone outside the fall and movement zones.
Position the door around the structural opening. Check the header for level, both side guides for plumb, the guide spacing for consistency, and the complete frame for square. Temporary supports must hold the assembly safely while the permanent anchors are installed.
Fix the top angle brackets and side guides to the approved supporting wall or steel frame, then complete the required lower/ground fixing points. Tighten the anchors in a controlled sequence and recheck alignment after tightening.
The installed door must be stable, level, and securely connected to the wall or installation frame. A twisted frame can create friction, uneven curtain travel, poor sealing, premature wear, and unreliable safety-sensor alignment.
Step 9: Install the Control Box and Complete Electrical Connections
Mount the control box in the approved location, where the operator can use the emergency stop safely and observe the door without standing in its travel path.
Electrical work must be completed by a qualified electrician using the model-specific wiring diagram. The manual requires the motor and controller to be safely grounded. It specifies a copper grounding conductor of at least 3.5 mm² and a grounding resistance below 10 ohms. It also calls for a leakage-protection device with a 0.03 A trip current, or an equivalent protected power system.
Observe these controller precautions:
- Verify that the supply matches the nameplate and project drawing.
- Isolate power for more than 10 minutes before wiring and wait for the board indicator to go out.
- Ground both the motor and controller.
- Do not install an electromagnetic contactor, absorbing capacitor, or other resistance-capacitance absorbing device between the controller and motor.
- Do not perform another withstand-voltage test on the controller.
- Keep cables protected, identified, and clear of moving parts.
- Do not energize the system with covers open unless the authorized commissioning procedure specifically requires it.
The supplied wiring diagram and applicable local code take priority if they differ from the general values above.
Step 10: Install Safety and Activation Devices
Install the photoelectric safety transmitter and receiver/reflector on opposite sides of the opening. Align them precisely, tighten their brackets, protect their cables, and make sure the beam is not blocked by the frame, floor conditions, stored materials, or normal traffic equipment.
Connect ordered activation devices to the terminals defined in the supplied controller diagram. Depending on the project, these may include:
- Push-button station
- Radar or motion sensor
- Geomagnetic/vehicle loop detector
- Pull-cord switch
- Appuyer sur la télécommande pour ouvrir la porte.
- Single-key cycle switch
- Safety bottom edge or airbag
- Interlock or building-management/automation signal
Do not bridge, bypass, or disable a safety input to make the door operate.
Step 11: Confirm Direction and Set Travel Limits
Clear the doorway and keep all personnel outside the movement zone. Use the controller’s authorized jog mode to confirm that the opening command moves the curtain upward and the closing command moves it downward.
Set the origin, fully open, and fully closed positions according to the controller version supplied with the door. Avoid setting the lower limit so aggressively that the bottom beam compresses, folds, or drives into the floor. Avoid setting the upper limit so high that the curtain, bottom beam, or wind bars enter an unsafe position in the header.
If the door moves in the wrong direction, does not find its encoder position, or reports a limit/encoder fault, stop commissioning and check the approved wiring and controller procedure. Do not repeatedly run the motor against an incorrect limit.
Step 12: Commission and Test the Door
Commissioning must prove that the complete system works safely, not just that the motor turns. Test at least the following:
- Open, close, stop, and emergency-stop buttons.
- Correct opening and closing direction.
- Fully open and fully closed limits.
- Photoelectric safety response during a closing cycle.
- Safety edge/airbag response, if fitted.
- Radar, loop detector, pull cord, remote control, interlock, or other ordered activation device.
- Curtain tracking in both guides.
- Bottom-beam position and sealing.
- Motor, reducer, and encoder operation without abnormal noise, vibration, or overheating.
- Several repeated cycles with the opening kept clear.
The manual notes that a misaligned photoelectric device may prevent the door from closing because the control system interprets the missing beam as an unsafe condition. Correct the alignment; never bypass the sensor.
Step 13: Fit Covers and Complete the Handover
After all tests pass, isolate the power as required, fit the motor and header covers, remove tools and drilling debris, and restore the work area.
Record:
- Door model and serial number
- Supply voltage and controller version
- Motor side
- Final limit settings
- Safety-device test results
- Activation devices fitted
- Installation and commissioning date
- Installer and electrician details
- Any approved deviations from the drawing
Give the owner the model-specific manual, wiring diagram, maintenance instructions, and service contact. Train authorized operators in normal controls, emergency stop, daily visual checks, safe use, and fault reporting. Keep the manual close to the door and readily accessible.

8. Common Installation Mistakes to Avoid
Assembling the Wrong Motor Side
Left-hand and right-hand motor arrangements are not interchangeable at the last minute. Confirm the approved drawing before connecting the guides and header.
Discarding the Shaft Pin or Rubber Pad
Small motor-mounting parts may be taped or packed separately. Identify them during the delivery inspection and install them as shown in the supplied manual.
Insufficient Shaft Engagement
The manual requires the door shaft to enter more than half the reducer depth. Inadequate engagement can cause poor alignment or drive damage.
Anchoring an Out-of-Square Frame
Tightening anchors before checking level, plumb, and square can twist the guides. Recheck alignment throughout the fixing sequence.
Leaving Cables Loose
Loose wiring can rub against the curtain, roller, shaft, or guide path. Use the internal cable slot and protect cables at metal openings.
Energizing Before Grounding and Safety Checks
The motor and controller must be grounded before operation. Safety devices must be installed and tested before normal cycling.
Commissioning with People in the Opening
No person should stand or pass beneath the door during installation, limit setting, or testing. Use an exclusion zone and a designated commissioning operator.
Bypassing a Photoelectric Sensor
A door that will not close may be responding correctly to a blocked or misaligned safety beam. Find and correct the cause instead of bypassing the input.
Changing Controller Parameters Without Authorization
Unapproved changes can alter direction, speed, limits, safety behavior, or interlock logic. Record approved settings and restrict access to trained personnel.
9. Basic Troubleshooting After Installation
The following checks complement this manuel d'installation de porte à grande vitesse; they do not replace diagnosis by a qualified service technician.
The Door Does Not Move
Confirm that the power supply is available and the emergency-stop button is released. Check the controller display and follow the model-specific fault procedure. Do not open the control enclosure or test live circuits unless you are a qualified and authorized technician.
The Door Opens but Will Not Close
Remove any obstruction from the doorway and inspect the photoelectric safety devices. Confirm that the transmitter is aligned with the receiver/reflector and that both brackets are secure. A faulty or misaligned safety device can intentionally prevent closing.
The Limits Are Incorrect or the Door Runs Slowly
Stop using the door and record the fault code shown on the controller. Incorrect limits, encoder faults, cable damage, loose aviation plugs, mechanical resistance, or controller settings may require remote guidance or service from the manufacturer.
There Is Abnormal Noise, Vibration, or Jamming
Press emergency stop, isolate the power, and keep the area closed. Inspect only within the user’s authorized scope. Contact a qualified service technician if the curtain, guides, bottom beam, wind bars, motor, reducer, encoder, or fixed points are damaged, loose, or deformed.
10. Maintenance After Installation
Correct installation is the beginning of the door’s service life, not the end of the work. This manuel d'installation de porte à grande vitesse recommends the following baseline:
- At least weekly: Inspect the curtain, wind-resistant ribs, bottom beam, guide rails, wall/ground fixing points, and mounting brackets. Stop using the door if any part is damaged, deformed, loose, or detached.
- Daily/as needed: Keep the curtain, frame, guide tracks, and operating area clean. Remove debris and stored objects from the doorway and under the curtain.
- Every 12 months: Re-tighten all fixing and connection screws, and verify that the opening and closing limits have not changed.
- After the first 12 months, every three months: Lubricate the transmission components as specified for the fitted motor and drive system.
- According to use frequency: Check motor noise, operating smoothness, limit positions, and the condition of the sealing brushes.
The actual service interval may need to be shorter in dusty, corrosive, wet, cold, high-cycle, or impact-prone environments. Follow the maintenance counter, motor manual, service agreement, and site preventive-maintenance plan.
Foire Aux Questions
Can I install a high speed door myself?
No. A high speed door should be installed and commissioned by qualified, trained personnel. Electrical wiring must be completed by a qualified electrician. Incorrect installation can create crushing, electrical, falling-component, or uncontrolled-movement hazards and may affect warranty coverage.
What tools are needed for high speed door installation?
The SEPPES manual lists 12, 13, 14, and 17 mm wrenches, Allen keys, and a drill set. Installers also need measuring and leveling tools, project-approved anchors, suitable lifting/access equipment, cable-management tools, electrical test equipment, lockout devices, and personal protective equipment.
How long does it take to install a high speed door?
Installation time depends on the door size and type, wall construction, access equipment, electrical preparation, number of safety and activation devices, and site readiness. Ask the installer to confirm a project-specific method statement and schedule after checking the opening and approved drawing.
How much headroom and side room are required?
Clearance depends on the door model, opening size, motor side, cover design, and accessories. Use the approved SEPPES project drawing rather than a generic dimension. Send the opening width and height, headroom, left and right side room, wall material, and site photos when requesting confirmation.
Why will my high speed door open but not close?
First check for an obstruction and confirm that the emergency stop is released. Then inspect the photoelectric safety sensor alignment. The controller may prevent closing when it does not receive a valid safety signal. Do not bypass the sensor; correct the alignment or contact a qualified technician.
How are the opening and closing limits set?
The installer confirms the direction in jog mode and sets the origin, fully open, and fully closed positions through the supplied controller procedure. The exact menu and limit method depend on the controller version, so use the model-specific manual and have a trained technician complete the setting.
How often should a high speed door be maintained?
The SEPPES manual calls for at least weekly condition checks, cleaning as needed, annual re-tightening of fixing and connection screws, and transmission lubrication every three months after the first 12 months. High-cycle or harsh environments may require shorter intervals.
Is this high speed door installation manual suitable for every rapid door?
No. It is a general guide for the SEPPES flexible-curtain high speed rolling door arrangement described above.
