A rail can be mounted on the rear panel of the power supply. The rail is included in the delivery of the coupling relay module.

The connector for the power supply and the screw-type terminal blocks for the process signals are part of the scope of the supply of the basic unit or the option modules.
Exception: :
6DR2803-8C interface module and 6DR2803-8P PROFIBUS-DP module.
The connectors have to be ordered separately.
