2.2.1 Devices with operating voltage type A
For the supply voltage, the following applies:
 Operating voltage
 Rated voltage range DC
24 V ... 48 V
 Voltage range DC incl. maximum tolerances
9,6 V ... 60 V
 The input voltage is electrically isolated from the housing.
 The device provides for voltage supply redundancy with no load
distribution.
 The supply voltage is connected via a 5-pin M12 connector (A coding, e.g.
ELWIKA 5012 PG7 from Hirschmann, supplied).
 Connect the supply voltage lines.
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.
