Status LEDs
The status of the supply voltages is signaled by two LEDs. A Status LED lights up green when the respective
supply voltage is present on the connector for the supply.

Conductor losses
Take into account the voltage drop on the supply line when planning a system. Avoid the voltage drop being
so high that the supply voltage at the box lies below the minimum permissible value. See
.
Variations in the voltage of the power supply unit must also be taken into account.
The following graph illustrates the dependence of the voltage drop on the core cross-section, current and
cable length:
