Preparing the front connector and the cables
Warning
Unintentional contact with live conductors is possible if the power supply module
and any additional load power supplies are switched on.
Always wire the S7-300 with the power turned off!
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.
