Connection - Siemens SINAMICS G130 Operating Instructions Manual

Connection

The built-in units are operated with high voltages.
All connection procedures must be carried out when the cabinet is de-energized.
All work on the device must be carried out by trained personnel only.
Death, serious injury, or substantial material damage can result if these warnings are not
taken into account.
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 device up to five minutes after it has
been disconnected due to the DC link capacitors. For this reason, the cabinet should not be
opened until a reasonable period of time has elapsed.
The operator is responsible for ensuring that the motor, converter, and other devices 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 an item of protective gear trips in a branch circuit, a leakage current may have been
disconnected. To reduce the risk of fire or an electric shock, the current-carrying parts and
other components in the cabinet unit should be inspected and damaged parts replaced.
When an item of protective gear trips, the cause of the trip must be identified and rectified.
