CAUTION
• When clamping wiring, use the included clamping material to prevent outside pressure being exerted on the
wiring connections and clamp firmly. When doing the wiring, make sure the wiring is neat and does not
cause the control box cover to stick up, then close the cover firmly.
• When attaching the control box cover, make sure you do not pinch any wires.
• After all the wiring connections are done, fill in any gaps in the through holes with putty or insulation (pro-
cured locally) to prevent small animals and insects from entering the unit from outside. (If they get in, they
could cause short circuits in the control box.)
• Outside the unit, separate the low voltage wiring (remote controller wire) and high voltage wiring (power
supply, ground, and other power wiring) at least 2in. so that they do not pass through the same place
together. Proximity may cause electrical interference, malfunctions, and breakage.

WARNING
Install a ground fault circuit interrupter.
The installation of a ground fault circuit interrupter is imperative for the prevention of electric shocks and fire
accidents.
• Fit the power supply wiring of each unit with a disconnect switch and a maximum overcurrent protective
device as shown in the drawing.
