7.3.2 Protective earth
The main earthing point is the center contact of the mains power inlet.
See rear view above in section 7.2.
Connection to protective earth is provided via the 3-wire IEC power cord.
The PRO-DAR models therefore must be connected to an earthed mains socket-outlet.
7.3.3 DC power connection
When operating on DC supply voltage as back-up power, together with mains supply
voltage, the PRO-DAR models are to be considered as a class I product with requirement of
connection to protective earth.
In this situation, connection to protective earth is provided via the mains power 3-wire
IEC power cord.
When operating on DC supply voltage exclusively, without mains supply connection,
the PRO-DAR models are to be considered as a class III product with no requirement of
connection to protective earth.
The PRO-DAR models are provided with a 3 pole Phoenix 7.62 mm header/plug
(DC inlet) for connection of 12 VDC, 24 VDC or 48 VDC voltage (depending on model).
The Phoenix header/plug is located on the rear side.
See rear view above in section 7.2.
Regarding Phoenix 7.62 mm cable connector, see chapter 9.1: "Spare parts".
Applied DC voltage must be within the range:
12 VDC models:
24 VDC models:
48 VDC models:
On the top plate next to the Phoenix header/plug are indicated the polarity of the
terminals:
DC supply voltage (if used) must be applied correctly to the PRO-DAR multicoupler.
If the polarization of the applied DC voltage is wrong, the DC fuse will blow.
The fuse must be replaced by a fuse according to chapter 9.1: "Spare parts".

Equipotential bonding
The center terminal of the 3-pole terminal block marked
bonding.
It is strongly recommended that all interconnected conductive accessible parts in a
system are connected to an equipotential bonding system, in order that no hazardous
touch voltage appears on exposed conductive parts.
