5.5 Installing the CPU
Introduction
The CPU executes the user program and uses the integrated system power supply to supply
the electronics of the modules via the backplane bus.
Requirements
The following preconditions have to be fulfilled to mount a CPU:
● The mounting rail is installed.
● In a system power supply located on the left next to the CPU, a U connector is inserted
on the back right.
Tools required
Screwdriver with 4.5 mm blade
Installing the CPU
1. Insert a U-connector into the back right on the CPU.
2. Install the CPU on the mounting rail and slide the CPU up to the left-hand system power
supply.
3. Ensure that the U-connector is inserted at the system power supply. Swivel the CPU in to
the rear.
4. Fasten the CPU (torque 1.5 Nm).
