4. Remove the cover plate on the DC cable compartment to expose the positive and negative DC
contacts and the Remote Control Terminal Block.
5. Prepare DC cable ends. Use ring terminals or, if using the optional D08241 Compression Lugs, leave
the cable ends bare.

6. Verify that the battery positive cable is not connected to the battery. Insert DC cables through the
strain reliefs and into the DC wiring compartment. Torque DC cable mounting bolts to 180 inch
pounds. Re-torque after 30 days. (If using the optional D08421 Compression Lugs, torque the Allen
mounting screw to 180 inch pounds and the Allen compression screw to 240 inch pounds. Re-torque
after 30 days.) Tighten the two strain relief cable clamps. Insert the four plastic plugs into the unused
cable openings.
7. Inspect the DC cable compartment to be sure no copper wire fragments are present after tightening
cables.
8. Route the negative DC cable to the battery. Verify cable polarity before proceeding. The fuse will be
blown and inverter can be damaged if the DC cables are reversed. Route the positive DC input cable
to the fuse and then to the battery. Protect cables with loom and use grommets or other appropriate
means where cables may contact hard, sharp edges. If possible, make the last DC connection at the
fuse to avoid causing a spark at the battery.
9. Connect Chassis Ground Bonding Lug to the vehicle chassis and/or earth ground using AWG No.8 or
larger copper conductor.
10. Verify that the inverter will turn ON but do not leave the inverter connected to the battery at this time
(remove the fuse). Final battery connections will be made after all control and AC output installation
issues have been inspected.
