You have two options for the Control Unit power supply:
Supply from the Power Module.
•
The sum of all of the currents of the following interfaces is limited to 0.8 A:
– Encoder power supply
– Drive-Cliq
– Power supply for the operator panel
– Analog outputs
– 24 V output voltage (terminal 9)
– 24 V PROFIBUS teleservice
– Resolver excitation
If a short circuit occurs at the output terminals when the CU is fully loaded, then the
Power Module overcurrent protection response, and the inverter is tripped with
overcurrent (Power Module and Control Unit).
External supply via terminals 31 and 32 with 20.4 ... 28.8 V DC, a maximum of 200

VA.
Use a DVC A power supply with Protective Extra Low Voltage (PELV) according to
EN 61800-5-1, Class 2.
Example: SITOP Power 5 A power supply unit
The 0 V of the power supply must be connected with low resistance to the PE of the
system.
The power supply is electrically isolated from the other terminal strip.
