10. WIRING EXAMPLE
10-1 HOW TO CONNECT WIRINGS
• Wire only after removing the control box lid as shown in
Fig. 14.
DANGER
• Use only specified wire and connect wires to terminals tightly.
Be careful that wires do not place external stress on termi-
nals. Keep wires in neat order so as to not to obstruct other
equipment. Make sure that the electric parts box lid closes
tightly. Incomplete connections could result in overheating,
and in worse cases, electric shock or fire.
WARNING
• Never connect power supply wiring to the terminal block for
remote controller wiring as this could damage the entire system.
CAUTION
• When clamping the wiring, use the included clamp material (9)
and (10) as shown in the Fig.14 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 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.
CAUTION
•
Do not, under any circumstances, connect the power sup-
ply wiring to the remote controller or transmission wiring
terminal block. Doing so can destroy the entire system.

and transmission wiring ] (Refer to Fig. 15)
•
Power supply wiring and Ground wire
Remove the control box lid.
Next, pull the wires into the unit through the conduit and
thread them through the insulation tube (accessory), then
connect to the terminal block (3P).
•
Remote controller and transmission wiring
Pull the wires into the unit through the wiring through hole and
connect to the terminal block (6P).
Be sure to put the part of the sheathed vinyl into the control box.

Sealing
material (12)
• Make sure to let a wire go through a wire penetration area.
• After wiring, seal the wire and wire penetration area to prevent
moisture and small creatures from the outside.
• Wrap the wire with the sealing material (12) as shown in the figure below.
(Otherwise, moisture or small creatures such as insects from
the outside may cause short-circuit inside the control box.)
Attach securely so that there are no gaps.
