Identify the connector positive and
return DC power connections. The
connections left to right are:
1—Positive DC power connection
2—Return DC power connection
3—Alarm Common
4—Alarm Input
2.
Measure two strands of twisted-pair
copper wire (18-to-20 AWG) long
enough to connect to the DC power
source.
3.
Using an 18-gauge wire-stripping
tool, strip each of the two twisted
pair wires coming from each
DC-input power source to 0.25 inch
(6.3 mm) ± 0.02 inch (0.5 mm). Do
not strip more than 0.27 inch (6.8
mm) of insulation from the wire.
Stripping more than the
recommended amount of wire can
leave exposed wire from the power
connector after installation.
4.
Remove the two captive screws that
attach the power and alarm
connector to the router, and remove
the connector.
5.
1—Power connector captive screws
On the power and alarm connector,
insert the exposed part of the
positive wire into the connection
labeled "V" and the exposed part
of the return wire into the
connection labeled "RT". Make
sure that you cannot see any wire
lead. Only wire with insulation
should extend from the connector.
NOTE:
Use the same method for
wiring the alarm connections.
