CHAPTER 2
Wiring
The FTR-120 is wired using five position terminal blocks.
The wiring pin-out for the FTR-120 module is shown in
Table 2.2.

Power A+ and Power A- are the power supply inputs.
Connect the positive lead of the power supply to the
terminal block Power A+ and the negative lead of the
power supply to the terminal block Power A-.
If a redundant supply is required, connect it to Power B+
and Power B-. Connect the positive lead of the redundant
power supply to the terminal block Power B+ and the
negative lead of the power supply to the terminal block
Power B-.
Network 1-4 are the network connections. Network 1
is the channel 1 network connection. Connect the first
network twisted pair to the terminal block NET1 positions.
The wiring is polarity-independent so it does not matter
which wire in the pair is connected to which position on
the terminal block. Connect the rest of the network twisted
pairs to the other channels. Leave any unused channels
unconnected.
NOTE: Terminals labeled EGND should be
connected to an earth ground.
Universal Power Supply
The universal power supply included in the repeater kit
allows for FTR-120 operation around the world. The
supply accepts any input voltage from 100 to 240 V AC,
and produces the required 12 V DC output. The male IEC
input allows for any mains lead adapter to be used with
the supply.
