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