Connecting the supply voltage to the CPU/interface module

Introduction
The supply voltage of the CPU/interface module is supplied by means of a 4-pin connector
plug located on the front of the CPU/interface module.
Power supply unit
Only use power supply units of type SELV/PELV with safe electrically isolated functional
extra low voltage (≤ 28.8 V DC).
Connection for supply voltage (X80)
The connections have the following meaning:
①
Ground of the supply voltage
②
Ground of the supply voltage for looping through (permitted value 10 A)
③
+ 24 V DC of the supply voltage for looping through (permitted value 10 A)
④
Spring release
⑤
+ 24 V DC of the supply voltage
1L+ and 2L+ and 1M and 2M are internally jumpered.

The maximum cross-section of the connection is 2.5 mm
1.5 mm
with the option of looping the supply voltage through without interruption, even when it is
unplugged.
Requirements
● Only wire up the connector plug when the supply voltage is turned off.
● Follow the wiring rules (Page 98).
