• option module types that you can use for the motor temperature sensor connection
• insulation or isolation level that each option module forms between its temperature sensor
connector and other connectors
• temperature sensor types that you can connect to each option module
• 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.

KTYPTCInsulation/IsolationType
No special requirement--xReinforced insulation between
the sensor connector and the
other connectors of the mod-
ule (including drive control unit
connector). –> No special re-
quirements for the thermistor
insulation level.
(The drive control unit is PELV
compatible also when the
module and a thermistor pro-
tection circuit are installed.)
CMOD-02
No special requirement--xCPTC-02
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 residual current devices.
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.
Note: You can use the Safe torque off function of the drive to implement the Emergency
stop function.
Implementing the Safe torque off function
See The Safe torque off function (page 193).
