Note
You can also use a 45
° angled connector instead of the straight connector shown.
Step 2
Use agency-approved compression (pressure) lugs for wiring terminations with a single 5/16"
mounting hole. Two-hole lugs should h
ave 1/4" mounting holes on 5/8" centers.
The PWR-2700W-DC-R ground lug is a right-angle lug. Check the terminations for the
appropriate wire size. Use a ground wire of at least 2 – 4 AWG. Use only copper wire.
Step 3
Slip on heat-shrink tubing on the wire ends before assembling the lugs on to the wire.
•
The lugs must be crimped with the proper tool.
•
The tubing should extend over the lug’s barrel and the wire's insulator.
Step 4
Shrink the tubing with a heat gun.
