Electrical installation

Important safety precautions

The devices 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 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 motor 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-conducting parts

and other components in the built-in 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.
