1.3Earthing and earth fault protection

The Honeywell NXL frequency converter must always be earthed with an earthing conductor connected to the earthing terminal

The earth fault protection inside the frequency converter protects only the converter itself against earth faults in the motor or the motor cable.

Due to the high capacitive currents present in the frequency converter, fault current protective switches may not function properly. If fault current protective switches are used they must be tested with the drive with earth fault currents that are possible to arise in fault situations.

WARNING

1

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.

2

Set the maximum motor speed (frequency) according to the motor and

the machine connected to it.

 

3

Before reversing the motor shaft rotation direction make sure that this

can be done safely.

 

4

Make sure that no power correction capacitors are connected to the

motor cable.
