Step 8 For easier cable-management, insert the positive cable first. Replace the ground lug with cable in the
following order:
a. Flat Washer
b. Ground lug with positive wire
c. Kepnut screw
Step 9 Tighten the Kepnut screw (use the screwdriver to tighten the ground screw in the terminal block to a
torque of 20+/–2 in-lbs / 2 per.) and repeat the same steps for the negative wires.
Note Secure the wires coming in from the terminal block so that they cannot be disturbed by casual contact.
Step 10 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.
Note The ground wire must contain a loop when securing it to the tie-wrap tab to prevent it from being
pulled out.
Step 11 Replace the terminal block plastic cover, which is slotted and keyed to fit correctly over the terminal
block; then tighten the black screw (use the screwdriver to tighten the screw to a torque of 5 in-lbs / 1
per.).
