7.2 Mounting the drive motor
The electrical installations and the checking of the direction of rotation
may only be carried out be a licensed electrician.
Connect the motor in compliance with the electro-technical regulation
Before mounting the motor, check the direction of rotation / linear travel of the EMA
actuator and the operation of the limit switches (if fitted). In order to do this:
1. Place the motor at the mounting position near the gearbox input.
2. Switch on the motor and check the direction of rotation.
3. Check the direction of rotation / linear travel by manually turning the gearbox input
shaft. Change the direction of the motor rotation if necessary by changing motor
connections.
4. Where necessary, attach coupling halves to motor shaft.
5. Mount motor onto gearbox input flange using screws provided.
