10. WIRING EXAMPLE
10-1 HOW TO CONNECT WIRINGS
•
Wire only after removing the control box lid as shown in
Fig. 17, refering to view A.
CAUTION
•
Be sure to attach power supply wiring and earth wire to the
control box with the clamp.
•
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 weak wiring
(remote controller and transmission wiring) and strong wiring
(earth wire and power supply wiring) by at least 50 mm so
that they do not pass through the same place together. Prox-
imity may cause electrical interference, malfunctions, and
breakage.
•
A main switch or other means for disconnection, having a
contact separation in all poles, must be incorporated in the
fixed wiring in accordance with relevant local and national
legislation.
Note that the operation will restart automatically if the main
power supply is turned off and then turned back on again.
[ 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 plate” attached to the control
box lid when laying electrical wiring.
•
Connect the remote controller and transmission wiring to
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.
[ Connecting electrical wiring, remote controller wiring,
and transmission wiring ] (Refer to Fig. 18)
• Power supply and Earth wiring
Remove the control box lid.
Next, pull the wires into the unit through the Wiring through
hole and connect to the terminal block (3P).
Be sure to put the part of the sheathed vinyl into the control
box.

Penetration area
• 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 strong and weak electric lines 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.
