Step 4:

Center the provided 4 1/2” x 1/2” dia. heat shrink tubing over

the power harness connectors (leaving at least 1 1/4” past

each connector). Be sure to keep the green ground wire for

the new harness out of the heat shrink as you will need to

run this ground to a different location.

Step 5:

Contract the heat shrink using a heat gun.

Step 6:

Tuck the power harness connection bundle between the bus

bar and the rack wall.

Step 7:

Route the green ground wire behind the bus bar, between

the rack wall and existing wires and land it at an open

terminal on any existing grounding bus in the rack using a square drive of phillips

screwdriver.

Step 8:

Use a wire tie to secure the ground wire to the wire bundle as it protrudes from

the heat shrink.
