Connecting the supply voltage

Introduction
The supply voltage of the CPU/interface module is supplied by means of a 4-pole connection
plug, which is located on the front of the CPU.
Connection for supply voltage (X80)
The connections of the 4-pole connector have the following meaning:
①

Figure 5-5
The maximum connector cross-section is 1.5 mm
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
To connect a wire without tools, follow these steps:
1. Strip 8 to 11 mm of the wires.
2. Seal or crimp the wire with end sleeves.
