Permissible cable lengths (shielded cables)
Without output reactor
Up to two parallel cables: each 100 m
Three parallel cables: each 80 m
If unshielded motor cables are used, a sine-wave filter must be installed.

Automatic restart function (option L32)
With option "Automatic restart" (L32), the system automatically restarts when the line supply
fails, irrespective of how long the line supply failure was. Alarms are acknowledged
automatically and the drive is restarted.
Voltage Sensing Module (VSM)
With the "Automatic restart" option, a Voltage Sensing Module VSM10 is integrated in the drive.
The VSM10 acquires the actual voltage values at the medium-voltage level upstream of the
circuit breaker.
When the medium voltage is restored after a power failure, this is detected by the open-loop/
closed-loop controllers via voltage transformers when the input-side circuit breaker has
dropped out. The voltage transformers should be located at the medium-voltage level upstream
of the circuit breaker.
For safety reasons, a time limit between the power failure and the maximum permissible power
restoration time is incorporated to ensure that the drive does not restart in an uncontrolled
manner. As a further warning, an acoustic signal is output when the drive restarts.
You can find further information on the Voltage Sensing Module (VSM10) in Section
"Description of the Components".
3.6.20
Line-side grounding switch (option L48)
When the make-proof grounding switch is closed, this option allows motor-driven make-proof
grounding switches that ground the line-side input voltage to be controlled automatically.
The motor-driven make-proof grounding switches are installed in an additional cabinet.
For safety reasons, the open-loop control system locks these make-proof grounding switches
so that they cannot be closed while voltage is still present. The control is integrated into the
protection and monitoring circuit. The make-proof grounding switches are closed automatically
when the standard make-proof grounding switch of the DC link is closed.
Observe the notes regarding the grounding switch provided in Chapter "Safety instructions
(Page 18)" and "Maintenance (Page 173)". Carefully comply with the 5 safety rules (Page 17).
