NOTE
•
For wiring to the control box, also see “Wiring Diagram”
label on the back of the control box cover.
•
Do not confuse remote controller wiring and transmission
wiring when connecting to the terminal block.
•
Fasten the wiring with accessory clamp (6).
•
If mounting a remote
controller on the unit, wire
as shown in the figure on
the right.
WARNING
•
Never connect power supply wiring to the terminal block
for remote controller wiring as this could damage the entire
system.
•
Use only specified wire and connect wires to the terminal
tightly. Be careful wires do not place external stress on ter
-
minals. Keep wires in neat order so as to not obstruct other
equipment. Make sure that the control box cover fits tightly.
Incomplete connections could result in overheating and, in
worse case, result in electric shock or fire.
CAUTION
•
To avoid a short circuit in the control box, be sure to apply
sealing material or putty (not included) to the wiring hole to
prevent the infiltration of water as well as insects or other
small creatures. Otherwise a short-circuit may occur inside
the control box.
•
When clamping the wirings, be sure no tension is applied
to the wire connections by using the included clamps. Also,
when wiring, make sure the control box cover fits snugly by
arranging the wirings neatly and attaching the control box
cover firmly. When attaching the control box cover, make
sure no wirings get caught in the edges. Pass the wirings
through the hole to prevent damage.
•
Make sure the remote controller wiring, the wiring between
the units, and other electric wiring do not pass through the
same locations outside of the unit, separating them by at
least 5”, otherwise electric noise (external static) could
cause mistaken operation or breakage.
CAUTION FOR WIRING
•
The indoor units in the same system can be connected to
the power supply from one branch switch. How ever, selec-
tion of branch switch, branch over current circuit breaker
and wiring size must be according to applicable legislation.
•
For connection to the terminal block, use a ring type crimp
style terminals with insulation sleeve or insulate the wirings
properly.

Wiring
•
If the above is not available, make sure to fulfill the following
requirements.
Connection of 2
wirings of same
size must be
carried out on
both sides.
Connection of
wirings of
different sizes is
prohibited.
Connection of 2
wirings on one
side is
prohibited.
(Abnormal heating may occur if the wirings are not tight-
ened securely.)
•
Use the required wirings, connect them securely and fix
these wirings securely so that external force may not apply
to the terminals.
Pass through hole
of remote
controller
fastening plate.
