Earthing 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.
