5.4 Mounting a load current supply module
Introduction
Load current supplies do not have a connection to the backplane bus of the S7-1500
automation systems and therefore do not use a configurable slot. The system power supply,
CPU, input and output circuits of the I/O modules and, if applicable, the sensor technology
and final controlling elements are supplied with 24 VDC through the load current supply.
Requirements
The mounting rail is installed.
Tools required
Screwdriver with 4.5 mm blade
Mounting a load current supply module
1. Install the load current supply on the mounting rail.
2. Swivel the load current supply to the rear.

3. Open the front cover.
4. Disconnect the power cable connector from the load current supply.
5. Screw the load current supply tight (torque 1.5 Nm).
6. Insert the already wired-up power cable connector into the load current supply.
