Grounding and ground fault protection

The SPI9000 inverter must always be grounded with a ground conductor connected to the ground terminal.

The ground fault protection inside the inverter only protects the inverter against ground faults in the motor or the motor cable.

Due to the high capacity currents present in the inverter, fault current protective switches may not function properly. If fault current protective switches are used, they need to be tested with ground fault currents present during possible fault situations.

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.
