Powering
The supply voltage of the remote powered amplifier (26...65 V AC) can be fed
through the output port (Figure 1 pos. 3) or the input port (Figure 1 pos. 1).
Make sure the remote powering jumper (Figure 4 pos. 11) is in the correct
position for remote powering. Refer to table 1 . External power can also be fed
through the amplifier into the network by moving remote powering jumpers of
the output ports to “on” position. Maximum feed-through current is
3 A per port.
Note that the external wiring connected to terminals that are hazardous live
requires installation by an instructed person. Because the amplifier is not
equipped with an all-pole mains switch, the powering shall be carried out in
accordance with all applicable installation rules.
The power intake of the remote powered amplifier may also be done externally
via the cable feed-through that is located on the upper right corner of the
amplifier (see Figure 3). The protective fuse is located on the left hand side of
the power supply board.

The locally powered amplifier is connected to the mains voltage of
180…255 V AC via its own power cord. The mains power supply is double
shielded and does not require separate grounding. However, the amplifier
housing has to be grounded from the grounding point. The supply voltage fuse
is located on the upper right corner of the amplifier, beneath the shroud of the
power supply unit.
