Electrical Installation - Siemens SINAMICS G130 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 when the cabinet is de-energized.
All work on the device must be carried out by trained personnel only.
Non-observance of these warnings can result in death, serious personal injury, or
substantial property damage.
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 five minutes after it has
been disconnected due to the DC link capacitors on the Power Module. 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 line reactor 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 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.
