Total operating current of the indoor unit
F0 = 15A or less *2
F0 = 20A or less *2
F0 = 30A or less *2
Apply to IEC61000-3-3 about max. permissive system impedance.
*1 The Ground-fault interrupter should support inverter circuit.
The Ground-fault interrupter should combine using of local switch or wiring breaker.
*2 Please take the larger of F1 or F2 as the value for F0.
F1 = Total operating maximum current of the indoor units × 1.2
F2 = {V1 × (Quantity of Type1)/C} + {V1 × (Quantity of Type2)/C} + {V1 × (Quantity of Type3)/C} + {V1 × (Quantity of Others)/C}

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 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.
* Take care when using strand wires, because beards may cause the wiring to
short out.
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
K L
the claw on the right side of the electrical parts box.
7) Fix the MA remote controller cable 4 on the fixing 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 fix 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
device, in all active conductors shall be incorporated in the fixed wiring.
5.2. Power supply wiring
• Install an earth line longer than other cables.
• Power supply codes of appliance shall not be lighter than design 245IEC57 or
227IEC57, 245 IEC 53 or 227 IEC 53.
• A switch with at least 3 mm, 1/8 inch contact separation in each pole shall be
provided by the air conditioner installation.
