The input voltage is electrically isolated from the housing.
You have the option of supplying the supply voltage redundantly, without
load distribution.
Use a power supply cable which is suitable for the voltage, the current and
the physical load.
Hirschmann recommends a wire diameter of 0.5 mm² to 0.75 mm²
(AWG20 to AWG18).
The supply voltage is connected via a 5-pin M12 connector (A coding, e.g.
ELWIKA 5012 PG7 from Hirschmann, supplied).
Connect the power supply cables.

WARNING
ELECTRIC SHOCK
The nominal voltage of 48 V specified for trains can temporarily exceed the
SELV threshold of 60 V based on EN 50155 para. 5.1.1.1. Use additional
measures to limit the surge voltage to 60 V or use a lower nominal voltage.
Failure to follow these instructions can result in death, serious injury,
or equipment damage.
