42 Electrical planning guidelines

Residual current device compatibility

The drive is suitable for use with residual current devices of Type B.
Note: As standard, the drive contains capacitors connected between the main circuit
and the frame. These capacitors and long motor cables increase the ground leakage
current and may cause nuisance faults in residual current devices.

Multidrives modules

￭
The drive is equipped with an internal ground fault protective function to protect the
unit against ground faults in the motor and motor cable. This function is not a
personnel safety or a fire protection feature. See the firmware manual for more
information.

Implementing the Emergency stop function

For safety reasons, install the emergency stop devices at each operator control station
and at other operating stations where emergency stop may be needed. Implement
the emergency stop according to relevant standards.

Cabinet-installed multidrives

￭
You can order the drive with an emergency stop function (option).
See the appropriate option manual for more information.

￭
For safety reasons, install the emergency stop devices at each operator control station
and at other operating stations where the emergency stop may be needed. Implement
the emergency stop according to relevant standards.
Note: You can use the Safe torque off function of the drive to implement the Emergency
stop function.
