NOTE

•

If the wiring is in a place where people it can be easily
touched by people, install a leak interrupter to prevent
electric shock.

•

When using a ground-fault circuit interrupter, make sure
to select one useful also to protection against overcurrent
and short-circuit.
If you use a leak interrupter which is designed for protect-
ing again ground faults, be sure to combine it with a wir-
ing interrupter or an load switch that has a fuse.

•

The length of the transmission wiring and remote control-
ler wiring are as follows.

ELECTRICAL CHARACTERISTICS

MCA: Min. Circuit Amps (A)

MFA: Max. Fuse Amps (A)

kW: Fan Motor Rated Output (kW) FLA: Full Load Amps (A)

10 WIRING EXAMPLE AND HOW TO SET

THE REMOTE CONTROLLER

10. 1 OPENING AND SHUTTING THE CONTROL BOX

AND CONNECTING THE WIRING

CAUTION

Be sure to power off before opening the control box.

•

Remove the control box lid and wire as shown in the figure
below (Refer to Fig 17 and 18 for details).

CAUTION

•

See “Electrical Wiring Diagram label” on the backside of the
lid of the control box for electric wiring work.

•

Be sure to attach the sealing material or putty (locally pro-
cured) to hole of wiring to prevent the infiltration of water as
well as any insects and other small creatures from outside.
Otherwise a short-circuit may occur inside the control box.

•

When clamping the wires, be sure no pressure is applied to
the wire connections by using the included clamping material
to make appropriate clamps. Also, when wiring, make sure
the lid on the control box fits snugly by arranging the wires
neatly and attaching the control box lid firmly.
When attaching the control box lid, make sure no wires get
caught in the edges. Pass wiring through the wiring through
holes to prevent damage to them.

•

Make sure the remote controller wiring, the wiring between
the units, and other electrical wiring do not pass through the
same locations outside of the unit, separating them by at least
50 mm, otherwise electrical noise (external static) could
cause mistaken operation or breakage.

10. 2 CONNECTING POWER SUPPLY WIRING AND

GROUND WIRING

•

Pass the power supply wiring and the ground wiring through
the wiring through-hole into the control box and secure with
the included clamping material after connecting the wires to
terminal blocks.

(Refer to Fig. 17)

<Precautions when laying power supply wiring>

[PRECAUTIONS]

[1] A circuit breaker capable of shutting down power supply to

the entire system must be installed.

[2] A single switch can be used to supply power to units on the

same system.
However branch switches, branch overload circuit interrupter
must be selected carefully.

[3] Fit the power supply wiring of each unit with a switch and

fuse as shown in the drawing.

Length of outdoor-indoor transmission wiring
… max 1000 m (total wiring length 2000 m)

Length of remote controller wiring between indoor unit
and remote controller … max 500 m
