WARNING
Do not connect or disconnect wires with power
applied.
4.
Connect the 24 vdc power wires and the LON
network cable to the appropriate points on J1, the
Power & LON Wiring terminal block. See Figure VII-
2.
COM 1 -
Communication network connections:
Connect to COM 2 terminals of the next
device on the loop, A to A and B to B.
COM 2 -
Communication network connections:
Connect to COM 1 terminals of the
previous device on the loop, A to A and B
to B.
24 VDC -
Connect the "+" terminal to the positive
side of the 24 vdc power source. (Both "+"
terminals are connected internally.)
Connect the "-" terminal to the negative
side of the 24 vdc power source. (Both "-"
terminals are connected internally.)
Connect the shield to the designated
"shield" terminal. (The two shield terminals
are connected internally.)
Do not
ground
any shield at the monitor / power
distribution cabinet. Insulate the shields
to prevent shorting to the device housing
or any other conductor.
5.
Connect a two wire cable between the AC input of
the power supply and terminals 1 and 4 on J3, the
AC input terminal block on the power supply
monitor. See Figure VII-3.
6.
Connect the “B” terminal on the power supply
monitor to the negative (–) side of the backup
battery. Connect a correctly sized circuit breaker or
disconnect switch in the battery circuit as shown in
Figure VII-4. If a circuit breaker is used, it must be
rated between 150% and 250% of the total load.
7.
Connect the “C” terminal on the power supply
monitor to the negative (–) side of the power supply.
8.
Wire the power distribution circuit breakers to the
output of the power supply. Circuit breaker ratings
must be between 150% and 250% of the full load
rating.
9.
Check all field wiring to ensure that the proper
connections have been made.
10. Set the LON address for the power supply monitor.
Refer to Figure VII-1 for rocker switch location.
Refer to “LON/SLC Device Address Switch Setting”
in the “Switch Setting” section (Section VIII) of the
Eagle Quantum system manual (form number 95-
8470) for complete information regarding the switch
setting procedure.
11. Connect the mounting frame to chassis (earth)
ground.
