Grounding and Ground Fault Protection

LCX9000 Liquid-Cooled Drives User Manual

January 2007

Grounding and Ground Fault Protection

The LCX9000 drive must always be grounded with a ground conductor connected to the ground terminal.

The ground fault protection inside the drive only protects the drive against ground faults in the motor or the motor cable. It is not intended for personal safety.

Due to the high capacity currents present in the drive, fault current protective switches may not function properly.

Motor and Equipment Safety

CAUTION

Before starting the motor, check that the motor is mounted properly and ensure that the machine connected to the motor allows the motor to be started.

CAUTION

Set the maximum motor speed (frequency) according to the motor and the machine connected to it.

CAUTION

Before reversing the motor, make sure that this can be done safely.

CAUTION

Make sure that no power correction capacitors are connected to the motor cable.

CAUTION

Make sure that the motor terminals are not connected to mains potential.

CAUTION

Before the Liquid-Cooled drive can be used to control the motor, the proper functioning of the liquid-cooling system must be ensured.
