Electrical Installation - Siemens Sinamics G120P Operating Instructions Manual

Electrical installation

Important safety precautions
Dangerous electrical voltage
The devices are operated with high voltages.
All connection work must be carried out in a no-voltage condition!
All work on the device must be carried out by trained personnel only.
Death, serious injury, or substantial material damage can result if these warning notices are
not observed.
Work on an open device must be carried out with extreme caution because external supply
voltages may be present. The power and control terminals may be live even when the
motor is not running.
Dangerously high voltage levels are still present in the cabinet up to 5 minutes after it has
been disconnected due to the DC link capacitors on the Power Module. For this reason, the
unit should not be opened until a reasonable period of time has elapsed.
The operator is responsible for ensuring that the du/dt filter with Voltage Peak Limiter and
other components are installed and connected in accordance with the recognized technical
rules in the country of installation and applicable regional guidelines. Special attention
should be paid to cable dimensioning, fuses, grounding, shutdown, disconnection, and
overcurrent protection.
If a protective device trips in a branch circuit, a fault current may have been interrupted. To
reduce the risk of fire or an electric shock, the current-conducting parts and other
components in the cabinet unit should be inspected and damaged parts replaced. When a
protective device trips, the cause of the trip must be identified and rectified.
