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, and input and output circuits of the I/O modules are supplied with 24 VDC through the
load current supply.
Requirements
The mounting rail is installed.
Tools required
