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 or below on the CPU / interface module.
Connection for supply voltage (X80)
The connections of the 4-pole connector have the following meaning:
①
②
③
④

Figure 7-5
The cable connector offers you the option of looping the supply voltage uninterrupted, even
when it is unplugged.
For the maximum wire cross-sections, observe the information in the tables of the Wiring
rules (Page 162).
Requirements
• Only wire the cable connector when the supply voltage is turned off.
• Observe the Wiring rules (Page 162).
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.
3. Insert the wire into the push-in terminal as far as it will go.
4. Push the wired connector into the socket of the CPU/interface module.
