Cisco 1900 Series Router Wiring Procedure for DC Input

To connect a router to a DC power source, perform the following steps.

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

Warning Use copper conductors only. Statement 1025

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

Tip Secure all power cabling when installing this unit to avoid disturbing field-wiring connections.

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

Step 2 Remove the plastic safety cover from the terminal block. Save the plastic safety cover, which you will put back on.

Step 3 Remove the negative and positive screws from the terminal block. You do not need to remove any other screws. Save the screws, which will be used to attach the wires to the terminals.

Step 4 Use the screws to connect the black wire to the negative terminal and the white wire to the positive terminal. Tighten the terminal screws to 8.0 ± 0.5 in-lb (0.9 ± 0.05 N-m). See Figure 4-14.

Caution Do not overtorque the terminal block contact screws.
