6.5 Connecting supply voltage to the interface module
Introduction
The supply voltage of the interface module is supplied via a 4-pole cable connector, that is
located on the front of the interface module.
Power supply unit
You must only use SELV/PELV type power supply units with protective extra-low voltage
with safe electrical isolation (max. 28.8 V DC).
The required power of the power supply unit depends on the power consumption of the
connected components.
Connection for supply voltage
The connections have the following meaning:
/

0
0
① Mass of the supply voltage
② Mass of the supply voltage for looping (permitted value 10 A)
③ + 24 V DC of the supply voltage for looping (permitted value 10 A)
④ Spring release
⑤ + 24 V DC of the supply voltage
1L+ and 2L+ as well as 1M and 2M are internally bridged.

. The cable connectors offer you the option
of looping the supply voltage uninterrupted, even when it is unplugged.
Requirements
● Only wire the cable connector when the supply voltage is turned off.
● Follow the wiring rules (Page 57).
Tools required
3 to 3.5 mm screwdriver
