Warning Incorrectly wiring the terminal block could create a dangerous shock hazard and could damage the power supply, power source, and the chassis components.

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.

Step 4 Provide strain relief for the DC-input cable by attaching two nylon ties around the cable and the metal bracket.

Step 5 Install the terminal block cover over the terminal block, and tighten the captive installation screws. Do not overtighten these screws. The recommended torque is 8.2 ± 0.4 inch-lb.

Warning To prevent a short-circuit or shock hazard after wiring the DC-input power supply, replace the terminal block cover.

Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle turn on power by moving the handle of the circuit breaker to the ON position.

Step 6 Connect the opposite end of the DC-input cable to the DC power source.
