To connect a router to a DC power source, perform the following steps:
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.
Warning Follow proper Lockout /Tagout Procedures as defined by your company in accordance with local and national laws (e.g. Title 29 CFR Part 1910.147).
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 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 Strip the wires to the appropriate length for the terminals. The strip length is 5/64 to 1/8 inch (2 to 4 mm) for Amp/Tyco No. 32957 terminals.
Step 3 Crimp the terminals to the power input and safety ground wires.
Step 4 Remove the plastic covers from the terminal block. Save the covers for reinstallation after you finish wiring.
Step 5 Connect the wires to the terminal block, starting with the safety ground wire. Connect each wire to the appropriate terminal as shown in Figure 1. Tighten the terminal screws to 8.0 ± 0.5 in-lb (0.9 ± 0.05 N-m).
Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028
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
Caution Dual sources with opposite-polarity grounding damage equipment.
Caution Caution Do not overtorque the terminal block contact screws. Recommended torque is 5.0 ± 0.5 in-lb (0.56 ± 0.06 N-m) for 2911 series routers, and 9 ± 1.0 in-lb (1.02 ± 0.11 N-m)
