2.2 Wiring the connectors for supply voltage
and signal contact
Note: Only connect the device to a power supply that complies to surge
voltage category II or lower.
2.2.1 Devices featuring supply voltage with the
characteristic value A
 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 and the signal contact are connected by means of a
5-pin M12 connector (“A”-coded, e.g. ELWIKA 5012 PG7 from
Hirschmann, included in the delivery).
You find the prescribed tightening torque in General technical data
section on page
37 .
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.
