Chapter 2: Installation December 20, 20042-10 LTPH-UM-1261-01Figure 2-1. Grounding LugStep Action
1 Looking at the HMS-318 List 3 rear panel, find the ground lug location (labeled BONDING WIRE MIN #10 AWG) on the upper right corner extension of the right panel (see Figure2-1).2 Measure between the telco-style rack and the HMS-318 List 3 Shelf the correct length of a #10 AWG (minimum) ground wire so that it reaches the ground lug location on the HMS-318 List 3 Shelf, and cut. Leave enough excess to allow for tying to the rack.3 Using wire strippers, strip about 5/8 inches of insulation from the ground wire that you will fasten to the ground lug.4 Next, using a crimping tool, insert the stripped end of the ground wire into the ground lug, and crimp.5 Attach the ground lug to the HMS-318 List 3 Shelf by placing the ground lug against the ground lug location, aligning the hole. Insert the ground-lug screw (#12 Hexhead) through the locking washer and then through the hole in the ground lug and the ground lug location on the HMS-318 List 3 Shelf. Ensure that the ground lug and attached ground wire does not interfere with the HMS-318 List Shelf or the telco-style rack.6 Tighten the screws to secure the locking washer and the ground lug to the ground lug location on the HMS-318 List 3 Shelf.7 Using wire strippers, strip about 5/8 inches of insulation from the other end of the ground wire. Using locally approved practices and fasten the stripped end of the ground wire to the telco-style rack.8 Use the tie-wraps (supplied) and secure the ground wire to the rack to prevent rotation.BONDING WIRE
