Step 15
Make sure the control box power switch is in the OFF
position. Unscrew and remove the control box cover and
slide the battery into position with its terminals to the left (see
illustration). Push battery down until it fits snugly in control
box. Connect the BLACK battery wire to the NEGATIVE
(–) battery terminal. Connect the RED battery wire to the
POSITIVE (+) terminal. Pay close attention to the color of
the wires. If the wires are connected incorrectly, the control
board will be damaged
.
NEVER
insert the battery with the
terminals to the right.
Mounting the Control Box
Step 16
Strip approximately 3/16" of insulation from each wire of the power
cable. Twist each exposed wire tightly (there are five [5] wires inside
the power cable sheath). Loosen sealing nut on strain relief hub at
bottom of control box. Insert power cable into control box through
strain relief. Thread approximately 4" of the power cable into the
control box and retighten sealing nut until the power cable locks into
place.
Step 14
Mount the control box using the nylon cable ties (provided)
or another secure mounting method. The control box must be
mounted at least 3 feet above the ground to protect it from
rain splash, snow, etc., and at least 3 feet from an ac power
source to prevent electrical interference.

Insert the stripped power cable wires into the appropriate terminals on
the FIRST OPERATOR terminal block. The green wire should be
inserted into the GRN terminal, the blue wire into BLU, the orange
wire into ORG, black wire into BLK, and the red wire into the RED
terminal.
Tighten the set screws against the end of the wires. A dab of
petroleum jelly on each terminal will help prevent corrosion.
HINT: A dab of household petroleum jelly
on the battery terminals will help prevent
corrosion.
