Connect the auxiliary voltage
Connect the auxiliary voltage 1-phase 230 VAC / 50 Hz
Connect the auxiliary voltage for SITOP, GSV, closed-loop control, open-loop control – for
example – to the terminal strip. The maximum cross section of the cables is 2.5 mm
With options C30 - C49, the auxiliary voltage can be drawn from the matching transformer. You
will find notes in the circuit manual of the drive.
Connect the auxiliary voltage 3-phase 400 VAC / 50 Hz
1. Connect the auxiliary voltage for fans, precharging, etc. to the terminal block. The maximum
2. To connect the cables, move the cover upward.
3. Attach the cables to the appropriate connections.
For detailed information, see "Terminal strips" and the circuit manual of the drive.

Connecting the encoder
Procedure
NOTICE
Damage caused by incorrectly connected external encoder
Components can be damaged if the external encoder is not connected or operated correctly.
● Only one measuring system can be connected to each sensor module. The sensor module
To connect the encoder, proceed as follows:
1. The five safety rules must be observed.
2. Route the cables from the encoder into the cabinet from below and to the customer terminal
3. Connect the signal line to the customer terminal strip. You will find details of this in the circuit
4. Connect the shield of the encoder cable directly to the shielding bus (serrated bar). It is
