￭ Connecting motor temperature sensor to the drive via an option module
This table shows:
• the option module types that you can use for the motor temperature sensor connection
• the insulation or isolation level that each option module forms between its temperature
sensor connector and other connectors
• the temperature sensor types that you can connect to each option module
• the temperature sensor insulation requirement in order to form, together with the
insulation of the option module, a reinforced insulation between the motor live parts and
the drive control unit.

Protecting the drive against ground faults
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.
￭ Residual current device compatibility
The drive is suitable to be used 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 circuit breakers.
Implementing the emergency stop function
You can order the drive with an emergency stop function.
See the appropriate manual for more information.
