6.5.6 Connect the auxiliary voltage
Connect the auxiliary voltage 1-phase 230 VAC / 50 Hz
Connect the auxiliary voltage for, e.g. SITOP, GSV, closed-loop control, open-loop control, to
the terminal strip ①. The maximum permissible conductor cross-section is 4 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 box ②. The
maximum permissible conductor cross-section is 50 mm
2
.
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.
