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.

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.

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.

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

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

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 connect the positive, negative, and ground wires according to the labels on the terminals.

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).
