Step

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 Figure 2-1).

 

 

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.
