Wire for 4000 W (right side of power supply bay) as follows:
a.
Place both plastic insulators over the terminal areas, aligning the circular holes in insulating cover
with terminal posts. The protective end flap on the plastic cover is opposite the wire entry area. The
protective end flap must fold down and cover the open side of the terminal (opposite side from wire
entry).
b.
Wrap the large perforated flaps around each pair of conductors, inserting each locking tab into rear
of slot. Pull the tab until the cover is secured around the power cabling trim and discard excess tab
plastic.
