You have two options for the Control Unit power supply:
● Supply from the Power Module
● External supply via terminals 31 and 32 with 20.4 ... 28.8 VDC.
Use a power supply with protective extra low voltage (PELV according to EN 61800-5-1),
Class 2.
The 0 V of the power supply must be connected to the PE of the plant/system through a low-
ohmic connection.
The power supply is electrically isolated from the control terminals.
