7.6.6 Voltage supply of the HS5E pilot control valve

The HS5E pilot control valve is supplied with 24 V DC. If this system-side voltage
supply is not present, you can use the VT-NE30-2X/ power supply unit according to
RE 29929. You connect the 24 V of the power supply unit to connections 1 (+24 V)
and 2 (L0) of the plug-in connector.
With the available connecting cable, this corresponds to the two black wires of the
1 mm² cross-section 3-pole cable. In this context, you must connect the wire labeled
"1" to +24 V and the one labeled "2" to L0 (Ground). The yellow/green wire must be
connected to ground.
