Connection - Siemens SINAMICS G120 Hardware Installation Manual

Connection

Install the converter so that you are compliant with local regulations for erecting and installing
low-voltage systems.
Note
Safety devices
Install suitable protective equipment between the line supply and converter.
Note
Operating displays for converter operation
If, when switching over a function from ON to OFF, an LED or other similar display is not lit or not
active; this does not indicate that the device is switched-off or in a no-current condition.
Observe the following product note about protection against indirect contact:
automatically shut down in the case of a fault according to DIN EN 60364-4-41 (VDE 0100-410).

Fire or electric shock due to unsuitable residual-current protective devices
The converter may create a current through the protective conductor. The current through the
protective conductor can cause the residual current device (RCD) or residual current monitor
(RCM) to incorrectly trip (nuisance trip). In the case of a ground fault, the fault current can
contain a DC component, which prevents the RCD or RCM from tripping, with the risk of
subsequent fire or electric shock.
• Use the protection and monitoring devices recommended in the documentation.
