Step 8 Tighten the Kepnut screw (use the screwdriver to tighten the ground screw in the terminal block to a torque of 8 in-lbs

Note Secure the wires coming in from the terminal block so that they cannot be disturbed by casual contact.
Step 9 Use tie wraps to secure the wires, so that the wires are not pulled from the terminal block by casual contact. Ti-wrap
studs are located below the power supply terminal block.
Step 10 Replace the terminal block plastic cover, which slides over the terminal block; then tighten the screws (tighten the screw
to a torque of 5 in-lbs / 1 per.).
