Wiring Procedure for Nominal 48 VDC Input
To connect the router to a DC power source, perform this procedure:
Step 1 Remove power from the DC circuit. To ensure that power is removed from the DC circuit, locate the circuit breaker for
the DC circuit, switch the circuit breaker to the OFF position, and tape the circuit-breaker switch in the OFF position.
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Statement 1003
Secure all power cabling when installing this unit to avoid disturbing field-wiring connections.
Tip
Step 2 Strip the wires to the appropriate length for the terminal block on the power supply.
Connect the DC power input wires to the terminal block, as shown in Figure 12.
Step 3
Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with
upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the
insulation and conductor. Statement 1002
Warning The illustration shows the DC power supply terminal block. Wire the DC power supply as illustrated. The proper
wiring sequence is ground to ground, positive to positive, and negative to negative. The ground wire should always
be connected first and disconnected last. Statement 239
Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no
exposed portion of the DC-input power source wire extends from the terminal block plug. Statement 122
The terminal arrangement on your router may not be identical to the arrangement shown in the figures. You must
Caution
connect the positive, negative, and ground wires according to the labels on the terminals.
Caution Do not overtorque the terminal block captive thumbscrew or terminal block contact screws. The recommended
torque is 8.0 ± 0.5 inch-lb (0.9 ± 0.05 N-m).
