Repair switch
Fig. 9/18
SINAMICS G110M repair switch
With the optional repair switch, the SINAMICS G110M can be
isolated easily from the line supply at the 400 V 3 AC level on the
input side. When this switch is used, no additional external com-
ponents are required in the 400 V feeder cable.
The repair switch can be locked with three locks. It can therefore
be locked to prevent unintentional restart of the drive system.
The repair switch is installed and delivered ready for use in
combination with our SIMOGEAR geared motor.

Note:
It is possible to install either a repair switch or a 24 V DC power
supply, but it is not possible to install both options on the same
unit.

into account the overload capability of the inverter.
Note
regarding use in compliance with UL regulations:
Fuses for use in North America must be UL-certified,
Class J fuses with a rated voltage of 600 V AC.
Short Circuit Current Rating (SCCR)
according to UL
Applies to industrial control panel installations according to
