5.1. Indoor unit (Fig. 5-1)
1) Remove the front panel, then remove the corner box from the lower right corner of
the indoor unit.
2) Remove the screw fixing the electric parts cover and remove the cover.
3) Connect the power cable and transmission cable to the terminal block.
• The electric parts box may have to be pulled forward during customer service etc.
Therefore, the wires must have some extra length.
4) After each wire is connected, fix it with pawls.
5) After the wiring is complete, re-assemble the indoor unit in the reverse order of its
disassembly
A means for the disconnection of the supply with an isolation switch, or similar de-
vice, in all active conductors shall be incorporated in the fixed wiring.
Power supply wiring
• Power supply codes of appliance shall not be lighter than design 245 IEC 53 or 227
IEC 53.
• A switch with at least 3 mm contact separation in each pole shall be provided by the
air conditioner installation.

Power cable size: more than 1.5 mm .
Note:
Install an earth longer and thicker than other cables.
5.2. Connecting remote controller, indoor and outdoor
transmission cables (Fig. 5-2)
• Connect indoor unit TB5 and outdoor unit TB3. (Non-polarized 2-wire)
The "S" on indoor unit TB5 is a shielding wire connection. For specifications about
the connecting cables, refer to the outdoor unit installation manual.
• Install a remote controller following the manual supplied with the remote controller.
• Connect the remote controller's transmission cable within 10 m using a 0.75 mm
core cable. If the distance is more than 10 m, use a 1.25 mm
1 MA Remote controller
• Connect the connector for MA remote controller. (Non-polarized 2-wire)
• DC 9 to 13 V between 1 and 2 (MA remote controller)
a MA remote controller cable (ACCESSORY 4)
2 M-NET Remote controller
• Connect the "M1" and "M2" on indoor unit TB5 to a M-NET remote controller. (Non-
polarized 2-wire)
• DC 24 to 30 V between M1 and M2 (M-NET remote controller)

K M-NET Remote controller
L Non-polarized 2-wire
Note:
*1 Put the transmission cable earth via the outdoor unit's earth terminal
the ground.
*2 If the remote controller cable exceeds 10 m, use a 1.25 mm
over the exceeded portion, and add that exceeded portion to within 200 m.
*3 The BC controller is required only for simultaneous cooling and heating
series R2.
5.3. Setting addresses (Fig. 5-4)
(Be sure to operate with the main power turned OFF.)
• There are two types of rotary switch setting available: setting addresses 1 to 9 and
over 10, and setting branch numbers.
Note:
Please set the switch SW5 according to the power supply voltage.
• Set SW5 to 240 V side when the power supply is 230 and 240 volts.
• When the power supply is 220 volts, set SW5 to 220 V side.
