-

When connecting wires of the same gauge, connect them 
according to the figure.

Use the specified electric wire. Connect the wire securely to the
terminal. Lock the wire down without applying excessive force to
the terminal. Use torques according to the table below.

-

When attaching the control box lid, make sure not to pinch 
any wires.

-

After all wiring connections are done, fill in any gaps in the 
casing wiring holes with putty or insulation material (field 
supply) thus to prevent small animals or dirt from entering the 
unit from outside and causing short circuits in the control box.

2

Keep total current of crossover wiring between indoor units less
than 12 A. Branch the line outside the terminal block of the unit
in accordance with electrical equipment standards, when using
two power wiring of a gauge greater than 2 mm

2

 (Ø1.6).

The branch must be sheathed in order to provide an equal or
greater degree of insulation as power supply wiring itself.

3

Do not connect wires of different gauge to the same grounding
terminal. Looseness in the connection may deteriorate the
protection.

4

Remote controller wiring should be located at least 50 mm away
from inter unit wiring and other wiring. Not following this
guideline may result in malfunction due to electrical noise.

5

For the remote controller wiring, refer to the "Installation manual
of the remote controller" supplied with the remote controller.

6

Never connect the inter unit wiring to the remote controller wiring.
This mistake could damage the entire system.

7

Use only specified wires and tightly connect wires to the
terminals. Be careful that wires do not place external stress on
the terminals. Keep wiring in neat order so that they do not
obstruct other equipment such as popping open the service
cover. Make sure the cover closes tight. Incomplete connections
could result in overheating, and in the worst case, electric shock
or fire.

IRING

 

EXAMPLE

For the wiring of outdoor units, refer to the installation manual
attached to the outdoor units.

Confirm the system type:

Pair type or multi system: 1 remote controller controls 1 indoor
unit (standard system).

Simultaneous operation system: 1 remote controller controls
2 indoor units (2 indoor units operate equally)

Group control: 1 remote controller controls up to 16 indoor units
(All indoor units operate according to the remote controller).

2 remote controller control: 2 remote controllers control 1 indoor
unit.

Pair type or multi system

(See figure 16)

Precautions

1

All transmission wiring except for the remote controller wiring is
polarized and must match the terminal symbol.

2

In case of group control, perform the remote controller wiring to
the master unit when connecting to the simultaneous operation
system (wiring to the slave unit is unnecessary).

3

For group control remote controller, choose the remote
controller that suits the indoor unit which has the most functions
(as attached swing flap).

4

When controlling the simultaneous operation system with
2 remote controllers, connect it to the master unit (wiring to the
slave unit is unnecessary).

5

Be sure to connect the wiring to the master unit when combining
with a simultaneous operating multi-type in group control.

6

Do not ground the equipment on gas pipes, water pipes,
lightning rods or crossground with telephones. Improper ground-
ing could result in electric shock.

Refer to the installation manual delivered with the decoration panel.

After installing the decoration panel, ensure that there is no space
between the unit body and decoration panel. Otherwise air may leak
through the gap and cause dew drop.
