6.5 Connect supply voltage to the CPU
Introduction
The supply voltage of the CPU is supplied by means of a 4-pole cable connector, which is
located on the front of the CPU.
Connection for supply voltage
The connections of the 4-pole connector have the following meaning:

① + 24 V DC of the supply voltage
② Mass of the supply voltage
③ Mass of the supply voltage for looping (current limited to 10 A)
④ + 24 V DC of the supply voltage for looping (current limited to 10 A)
⑤ Spring opener (one spring opener per terminal)

. The cable connector offers 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 59).
Tools required
3 to 3.5 mm screwdriver
Tool-free connection of cables: multi-wire (stranded), with end sleeve or ultrasonic compressed
1. Strip 8 to 11 mm of the wires.
2. Seal or crimp the wire with end sleeves.
3. Insert the wire into the push-in terminal as far as it will go.
4. Push the wired connection plug into the plug socket of the CPU.
