Given in the following table are the indicators of the load power
supply and their significance:

Indicators

Significance
5 green LEDs Outputs 1L+ to 5L+ are operating correctly
1 red LED Short-circuit at outputs 2L+ to 5L+
The voltage selector switch is on the basic module and is set to 230 V
when delivered (see switch labelling).
Signal lines for the load power supply module must be connected via
a front connector. The front connector is not supplied with the power
supply module and must be ordered separately. You have a choice of
crimp connections and screw connections. The order numbers can be
found in the ordering information.
The front connector hooks into the lower end of the module; it should
be swivelled up and screwed to the module.
