[ PRECAUTIONS ]
1. Use ring-type crimp-style terminals for connecting
wires to the power supply terminal board. If unavail-
able, observe the following points when wiring.
• Do not connect wires of different gauge to the
same power supply terminal. (Looseness in the
connection may cause overheating.)
• When connecting wires of the same gauge, con-
nect them according to the righthand figure.
• Use the specified electric wire. Connect the wire
securely to the terminal. Lock the wire down with-
out applying excessive force to the terminal.
(Tightening torque: 1.31N · m ± 10%)
2. Keep total current of crossover wiring between
indoor units less than 12 A.
Branch the line outside the terminal board of the unit in accordance with electrical equipment standards,
when using two power wiring of a gauge greater than 2 mm
The branch must be sheathed to provide an equal or greater degree of insulation as the power supply wir-
ing itself.
3. Do not connect wires of different gauge to the same grounding terminal. Looseness in the connection may
deteriorate protection.
4. Keep transmission wiring at least 50 mm away from power supply wiring. The equipment may malfunction
if subjected to electrical (external) noise.
5. For remote controller wiring, refer to the "INSTALLATION MANUAL OF REMOTE CONTROLLER"
attached to the remote controller.
6. Never connect power supply wiring to the terminal board for transmission wiring. A mistake of the
sort could damage the entire system.
7. Use only specified wire and tightly connect wires to terminals. Be careful wires do not place external stress
on terminals. Keep wiring in neat order and so as not to obstruct other equipment such as popping open
the service cover. Make sure the cover closes tight. Incomplete connections could result in overheating,
and in worse case, electric shock or fire.
9-2 HIGH CEILING INSTALLATION
(1) This unit can be installed in ceilings up to 3.8 meters high. If the ceiling height exceeds 2.7 meters, how-
ever, connect the connector on the terminal board (A2P) of indoor units as shown in the figure below.
