WARNING
• Never connect power supply wiring to the terminal block for
remote controller wiring as this could damage the entire
system.
NOTE
NOTE
• When clamping the wiring, use the included clamp material
(9) and (10) as shown in the Fig.14 to prevent outside pres-
sure 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 lid to stick up, then close the
cover firmly. When attaching the control box lid, 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. Prox-
imity 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" attached to the
control box lid when laying electrical wiring.
• Connect the remote controller and transmission wiring their
respective terminal blocks.Do not, under any circum-
stances, connect the power supply wiring to the remote
controller or transmission wiring terminal block. Doing so
can destroy the entire system.
