5.1. Indoor unit (Fig. 5-1,5-2)
1) Remove the front panel, then remove the corner box from the lower right corner
of the indoor unit.
2) Remove the screw fi xing 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) Connect the connector for MA remote controller.(Non-polarized 2-wire)
5) Connect the attached cable 5 to the CN90 on controller board in the electrical
parts box.
* Be sure to connect in case of using MA/M-NET Remote controller.
6) Fix the MA Remote controller cable 4 and the cable 5 with the clamp through
the claw on the right side of the electrical parts box.
7) Fix the MA remote controller cable 4 on the fi xing clamp with the cable running
along the down side of the terminal block.
8) Fix the cable 5 with the attached band 6.
9) Bring out the lead wire on the back side of the front panel to the corner box side.
Put back the electrical cover and front panel.(Do not pull the lead wire strongly.)
10) After connecting the connectors (yellow 9-pole) on the indoor unit and front
panel, slide the glass tube and fi x it with the attached fastener 7 at which the
connector joint part is not exposed.
* Be sure to connect in case of using MA/M-NET Remote controller.
11) Fix each wire with the clamp for on-site wiring under the electrical parts box
and put the corner box cover back.
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 fi xed wiring.
Selecting non-fuse breaker (NF) or earth leakage breaker (NV).
For breaker, means shall be provided to ensure disconnection of all active phase
conductors of the supply.
Power supply wiring
• Install an earth longer than other cables.
• Power supply codes of appliance shall not be lighter than design 60245 IEC 53 or
60227 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

5.2. Connecting remote controller, indoor and outdoor
transmission cables (Fig. 5-4)
• Connect indoor unit TB5 and outdoor unit TB3. (Non-polarized 2-wire)
The "S" on indoor unit TB5 is a shielding wire connection. For specifi cations about
the connecting cables, refer to the outdoor unit installation manual.
Note:
As for PKFY-P . BM series, TB5 has two terminals and does not have S terminal.
The earths of shielding wires are crimping-connected. Insulate the connected
parts with insulating tapes and so on.
• 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
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)
3 Wireless remote controller
• When more than two units are run under group control using wireless remote
controller, connect TB15 each with the same number.
• To change Pair No. setting, refer to installation manual attached to wireless remote
controller. (In the default setting of indoor unit and wireless remote controller, Pair No.
is 0.)
