How to connect wiring
(See figure 25)
Power supply wiring and ground wire
Remove the switch box lid and connect wires of matching
number to the power supply terminal block (3P) inside. (See E).
And connect the ground wire to the terminal block. In doing this,
pull the wires inside through the hole and fix the wires securely
with a field supplied clamp. (See B).
Give enough slack to the wires between the clamp and power
supply terminal block.
Transmission wiring and remote controller wiring.
Remove the switch box lid and pull the wires inside through the
hole and connect to the terminal block for remote controller (6P).
(See C and A). (No polarity) Securely fix the remote controller
cord with a field supplied clamp.
Give enough slack to the wires between the clamp and the
terminal block for the remote controller.
After connection, attach sealing material. (See D).
Be sure to attach it to prevent the infiltration of water from the
outside. (See D).

infiltration of water as well as any insects and other small
creatures from the outside. Otherwise a short-circuit may
occur inside the switch box.

Precautions
1 Observe the notes mentioned below when wiring to the power
supply board.
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, 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. (tightening torque 1.31 N•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 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 cords and wires connecting the units should
be located at least 50 mm away from power supply 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 power supply wiring to the terminal board for
transmission 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 worse case, electric shock
or fire.
