External power supply
The external power supply is needed only if you want to connect an external back-up power
supply for the drive control unit.
Note:
Frames R1...R5 need CMOD-01 for connecting external power supply, frames R6...R9
have corresponding terminals 40 and 41 on the control unit.

General cabling instructions

Obey the instructions given in chapter Planning the electrical installation.

Wiring

Connect the external control cables to the applicable module terminals. Ground the outer
shield of the cables 360 degrees under a grounding clamp on the grounding shelf of the
control cables.
Motor thermistor connection example
1)
The PTC input is reinforced/double insulated. If the motor part of the PTC sensor and wiring
are reinforced/double insulated, voltages on the PTC wiring are within SELV limits.
If the motor PTC circuit is not reinforced/double insulated (ie, it is basic insulated), it is
mandatory to use reinforced/double insulated wiring between the motor PTC and CMOD-02
PTC terminal.
