Guidelines for planning the electrical installation 59
Protecting the drive against ground faults
The drive is equipped with an internal ground fault protective function to protect the drive
against ground faults in the motor and motor cable in TN (grounded) networks. This is not
a personnel safety or a fire protection feature. The ground fault protective function can be
disabled with a parameter, refer to the firmware manual.
Residual current device compatibility
The drive is suitable to be used with residual current devices of Type B.
Note: The EMC filter of the drive includes capacitors connected between the main circuit
and the frame. These capacitors and long motor cables increase the ground leakage
current and can cause fault current circuit breakers to function.
Implementing the emergency stop function
The drive can be equipped with emergency stop function of stop category 0. For safety
reasons, install the emergency stop devices at each operator control station and at other
operating stations where emergency stop can be needed.
Note: Pressing the stop key on the control panel of the drive, or turning the operating
switch of the drive from position “1” to “0” does not generate an emergency stop of the
motor or separate the drive from dangerous potential.
See the user’s manual for the wiring, start-up and operation instructions.
