Connecting Electrical Wiring - Daikin R410A Installation Manual

CAUTION
• 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.
• Outside the unit, separate the low voltage wiring (remote controller wiring) and high voltage wiring (ground wire and power
supply wiring) at least 5in so that they do not pass through the same place together. Proximity may cause electrical interfer-
ence, malfunctions, and breakage.
[ PRECAUTION ]
• See also the "Electrical Wiring Diagram Label" when wiring the unit for power supply.

Be sure to put the part of the sheathed vinyl into the control box.
WARNING
• Do not use tapped wires, stranded wires, extension cords, or starburst connections, as they may cause overheating,
electrical shock, or fire.
