16 A breaker (Tripping current = 8 × 16 A at 0.01s)
*3 Current sensitivity is calculated using the following formula.
G1 = (V2 × Quantity of Type1) + (V2 × Quantity of Type2) + (V2 × Quantity of Type3) + (V2 × Quantity of Others) + (V3 × Wire length [km])
G1 Current sensitivity
30 or less 30 mA 0.1 sec or less
100 or less 100 mA 0.1 sec or less
Caution:
Do not use anything other than the correct capacity breaker and fuse. Using fuse, wire or copper wire with too large capacity may cause a risk of malfunction
or fire.
9.2. Connecting remote controller, indoor
and outdoor transmission cables
• 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 control-
ler.
• Connect the "1" and "2" on indoor unit TB15 to a MA remote controller. (Non-
polarized 2-wire)
• Connect the "M1" and "M2" on indoor unit TB5 to a M-NET remote controller.
(Non-polarized 2-wire)
• Connect the remote controller's transmission cable within 10 m [32 ft] using a
0.75 mm [AWG18] core cable. If the distance is more than 10 m [32 ft], use a
2
1.25 mm 2 [AWG16] junction cable.

9.1. Power supply wiring
• Power supply cords of appliances shall not be lighter than design 245 IEC 57, 227 IEC 57, 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.

9.3. Connecting electrical connections
Please identify the model name of the operation manual attached on the terminal
box cover with that shown on the rating name plate.
1. Remove the screw (1pc) holding the cover to dismount the cover.
[Fig. 9.3.1] (P.6)
2. Open knockout holes
(Recommend to use a screwdriver or the like for this work.)
[Fig. 9.3.2] (P.6)
3. Fix power source wiring to terminal box by using buffer bushing for tensile
force. (PG connection or the like.) Connect transmission wiring to transmis-
sion terminal block through the knockout hole of terminal box using ordinary
bushing.
