Move The Front Connector Into Wiring Position - Siemens SIMATIC S7-300 Hardware And Installation Manual

Requirement
The modules (SM, FM, CP 342-2) are mounted on the rail.
Preparing the front connector and the cables
Warning
You can come into contact with live wires if the power supply module and any
additional load power supply units are connected to the mains.
You should therefore disconnect the S7-300 from the power supply before starting
the wiring. Once you have wired the modules, close all the front panels. You can
then switch on the S7-300 again.
1. Open the front panel (1).

2. Move the front connector into wiring position (2).

Slide the front connector into the signal module until it latches. The front
connector still protrudes from the module in this position.
Advantage of the wiring position: Easy wiring.
In this wiring position the front connector does not contact the module.
3. Strip the leads to a length of 6 mm.
4. Crimp on the cable end sleeves, e.g. for terminating 2 conductors on 1 terminal.
