7Mechanical installation
Warning – Explosion hazard!
 Check the atmosphere for explosion hazards before commencing installation tasks.
Requirements
The permissible loads on walls, mountings, connection and transmission elements must not
be exceeded even for maximum holding or locking torque (▶ observe technical data).
Connection elements:
▶ Use self-locking
connection elements with
a minimum strength of
800 N/mm2 (8.8).
▶ Use a screw that
precisely fits the hole.
▶ Use adequately
dimensioned washers for
elongated holes.

Installation
The following descriptions refer to a door which is not further defined. The door
manufacturer's specifications must also be observed.
Warning – Injury or danger to life possible!
Use a lifting device with sufficient load-carrying capacity for installation tasks.
▶ Completely grease the door shaft.

8Electrical installation
Warning – Danger to life from electrical shock!
Disconnect the cables (mains OFF) and check that the supply is off
Observe the applicable regulations and standards
Ensure proper electrical connection
Use suitable tools
Carrying out the electrical installation
Remove the cover. Remove the cover.
Connect motor/limit switch connection cable

14
Protection against overload
Motor protection switch / motor protection relay mains operation
The "Ex" motor must be protected against overload by means of a motor protection switch or
a motor protection relay. Only use motor protection relays with manual reset. Short-circuit
protection is also required.
The excess current setting must be selected such that the motor is disconnected from the
mains within the heating time tE. The actual tripping time tA at a relative operating current of IA
/ IN must be calculated on the basis of the tripping characteristic of the excess current relay. It
must be ensured that tA < tE is given.
Completing the electrical installation
Install cable entries and/or cable glands.

15
9Limit switch setting
The limit switch setting defines the final limit positions OPEN and CLOSE.
Requirement
The door should open by pressing the OPEN
push-button of the control. If the door closes,
L1 and L2 must be swapped in a de-
energised state.
Setting of OPEN final limit position
Open to the desired OPEN final limit position
using the OPEN push-button.
Turn the cam of the S3 OPEN limit switch to
the centre of the switch plunger ①.
Tighten the screw of the cam ②.

16
Check the door position:
Close the door ① until the cam is released
and open it again ② until the OPEN final limit
position is reached.
The OPEN final limit position can be
corrected by following the fine adjustment
procedure. Check the door position after each
correction.
The S1 EMERGENCY OPEN limit switch is preset by the setting of the OPEN final limit
position. The door must stop without posing any risks should the rotating direction be
incorrect or should there be a fault with the S3 OPEN limit switch. Follow the fine adjustment
procedure to correct the switching point of the limit switch as needed.
Setting of CLOSE final limit position and auxiliary limit switch
The same setting procedure applies as for setting the OPEN final limit position.

12 Emergency manual operation (emergency hand crank)
The emergency manual operation is designed for opening or closing the door without power
supply. Its activation interrupts the control voltage. Electrical operation is no longer possible.
Warning – Injuries due to incorrect operation or falling objects!
Switch off voltage.
Adopt a secure position.
For drive units with brake, the emergency manual operation must be carried out
against the closed brake.
Warning - Danger of the door dropping!
If you need to apply more than the permissible force of 390N (according to DIN EN
12604/DIN EN 12453) to move the door by emergency manual operation, this
indicates a stalling on the drive unit or door. Releasing the stalling may cause the
door to drop.
Adopt a secure position.
For drive units with brake, the emergency manual operation must be carried out
against the closed brake.
Caution – Damage to components!
Do not move the door beyond the final limit positions.

19
Plug in the crank and turn until it engages
(①). Open or close by turning the crank (②).
After use, the crank may be attached to the
drive unit.
▶ Attach as illustrated.

13 Completion of initial operation / inspection / operation
Check the following components and after that, mount all covers.
Gearbox
Check drive unit for oil loss (some drops are not critical). Protect output shaft permanently
against corrosion.
Oil loss!
Oil loss may render explosion protection ineffective. Oil maintenance is
inadmissible.
Motor
Check motor for defective bearings
Mounting
Check all mounting elements (consoles, torque mounts, screws, retaining rings etc.) for
tightness and impeccable condition.
Electric wiring
Check connection cables and cables for damage or pinches. Check screw connections for
correct seating and electrical contact.
Emergency actuation
Function to be checked in a de-energised state. Check for correct functioning is to be carried
out between the final limit positions only.
