Powering 

The supply voltage of the remote power

ed amplifier (26...65 V AC) can be fed 

through either f the output ports (Figure 1 pos. 3 & 4) or the input port (Figure 1 

pos. 1). Make sure the remote powering jumpers (Figure 4 pos. 20 & 21) are in 

the correct positions for remote powering. Refer to chapter ‘Jumper settings’

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 (6 A total). When F connector is used, a remote 

current should be lower than 2 A. 
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  CXE180 amplifier  is connected to the main voltage of 

180

…255 V AC via its own power cord. The 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 

(T3.15 A / 250 

V)

  is located on the upper right corner of the amplifier, 

underneath the remote cable connector (Figure 3)
