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
(procured locally) to prevent small animals and insects from entering the unit from outside, as they
could cause short circuits in the control box.
• Outside the unit, separate the low voltage wiring (remote controller wiring and wiring between units)
and high voltage wiring (ground and other power wiring) at least 2 in. so that they do not pass through
the same place together. Proximity may cause electrical interference, malfunctions, and breakage.
