DANGER
Use only specifi ed wire and connect wires to terminals
•
tightly. Be careful that wires do not place external stress on
terminals. Keep wires in neat order so as to not to obstruct
other equipment. Make sure that the terminal block box
cover closes tightly. Incomplete connections could result in
overheating, and in worse cases, electric shock or fi re.
WARNING
Never connect power supply wiring to the terminal block for
•
remote controller wiring as this could damage the entire
system.
CAUTION
When doing the wiring, make sure the wiring is neat and
•
does not cause the terminal block box cover to stick up, then
close the cover fi rmly. When attaching the terminal block box
cover, make sure you do not pinch any wires.
Outside the air conditioners, separate the low voltage wiring
•
(remote controller and transmission wiring) and high voltage
wiring (ground wire and power supply wiring) at least 5 in. so
that they do not pass through the same place together.
Proximity may cause electrical interference, malfunctions,
and breakage.
[ PRECAUTIONS ]
Refer to the “REMOTE CONTROLLER INSTALLATION
•
MANUAL” on how to install and lay the wiring for the remote
controller.
See also the “Wiring Diagram Label” located inside the unit’s
•
fan housing.
Connect the remote controller and transmission wiring their
•
respective terminal blocks.
CAUTION
Do not, under any circumstances, connect the power
•
supply wiring to the remote controller or transmission
wiring terminal block. Doing so can destroy the entire
system.
