Grounding and ground fault protection
The SLX9000 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 itself against ground
faults in the motor or the motor cable.
Due to the high capacity currents present in the drive, 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.
