Connecting-Up - Siemens SINAMICS G12 Hardware Installation Manual

Connecting-up

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.
To protect against indirectly touching part of the motor circuit of an inverter and to automatically
shut down in the case of a fault according to DIN EN 60364-4-41 (VDE 0100-410).

Electric shock due to faulty contact protection
Due to faulty contact protection, the power connections of the inverter may be openly
accessible. Touching live power connections can result in death or severe injury.
● Make the openings for the inverter power connections just large enough for the cables to
● Cover power connections that are not used so that they cannot be touched.
● Use the dummy plugs provided in the accessory pack for unused terminals.
Fire or electric shock due to unsuitable residual-current protective devices
The inverter 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.
