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.
