Electrical connection

See Section 5.2.4 for warnings and notes relating to electrical connection!

1. Unscrew the hood screws and remove the hood.

2. Establish the electrical connections in accordance with the circuit diagram; see fig. 20.

– Connect terminals 18, 19 and 20 in accordance with

requirements; voltage < 50 V.

3. Determine the direction of rotation and, if necessary, correct it.

Determining the direction of rotation

The internal wiring means that the direction of rotation (looking through the drive towards the output shaft) and limit switches are assigned as follows:

• If the mains voltage is present at terminal 2, the output shaft

rotates anticlockwise (in the direction "open/max.").

– This direction of rotation is restricted by the upper switch

(max.). If the switch is activated, the mains voltage is present at terminal 4.

• If the mains voltage is present at terminal 3, the output shaft

rotates clockwise (in the direction "close/min.").

– This direction of rotation is restricted by the lower switch

(min.). If the switch is activated, the mains voltage is present at terminal 5.

• If the drive rotates in the opposite direction to the control

commands, swap over the connections of terminals 2 and 3.

Warning The internal wiring of the drive must never be

modified.

Close the hood again and tighten the hood screws.
