Connection of power supply voltage
5.3.1 Mains connection
The PRO-ARU…G is provided with a 3-terminal IEC60320-1 C14 (male) inlet for
mains power connection. The mains inlet is located on the rear side. See rear view above.
Applied mains voltage must be within the range 207 – 264 VAC (230 – 240 V ±10 %).
A 3-wire IEC power cord must be used for mains voltage connection.
5.3.2 Protective earth
The main earthing point is the center contact of the mains power inlet.
See PRO-ARU…G rear view above.
Connection to protective earth is provided via the 3-wire IEC power cord.
The PRO-ARU…G therefore must be connected to an earthed mains socket-outlet.
5.3.3 DC power connection
The PRO-ARU…G is provided with a 3 pole screw terminal block (DC inlet)
for connection of 12 VDC voltage or 24 VDC voltage (depending on model).
The terminal block is located on the rear side. See rear view above.
Applied DC voltage must be within the range 10.8 – 14.4 VDC (12 VDC model)
or 18 – 28 VDC (24 VDC model).
On the top plate next to the screw terminal block are indicated the polarity of the
screw terminals:
DC supply voltage (if used) must be applied correctly to the receiver multicoupler.
If the polarisation of the applied DC voltage is wrong, the DC fuse will blow.
The fuse must be replaced by a fuse according to chapter 7.1: “Spare parts”.
