a. Using wire strippers, strip the rubber
jacket from both ends of cable to reveal
about 1.57in (40 mm) of the wires
inside.
b. Strip the insulation from the ends of the
wires.
c. Using a wire crimper, crimp u-lugs on the
ends of the wires.
PAY ATTENTION TO LIVE WIRE
While crimping wires, make sure you clearly
distinguish the Live (“L”) Wire from other wires.
2. Unscrew the electrical wiring cover and
remove it.
3. Unscrew the cable clamp below the terminal
block and place it to the side.
4. Match the wire colors/labels with the labels on
the terminal block, and firmly screw the u-lug
of each wire to its corresponding terminal.
5. After checking to make sure every connection
is secure, loop the wires around to prevent
rain water from flowing into the terminal.
6. Using the cable clamp, fasten the cable to the
unit. Screw the cable clamp down tightly.
7. Insulate unused wires with PVC electrical tape.
Arrange them so that they do not touch any
electrical or metal parts.
8. Replace the wire cover on the side of the unit,
and screw it in place.
