
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 0.75 mm² to 1.0 mm²
(AWG18 to AWG16).

The supply voltage is connected via a 5-pin 7/8" connector.
See “Accessories” on page 42.

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 this instruction can result in death, serious injury, or
equipment damage.
