*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])
Current sensitivity
G1
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
2
[AWG18] core cable. If the distance is more than 10 m [32 ft], use a
1.25 mm
[AWG16] junction cable.

The MA remote controller and the M-NET remote controller cannot be used at
the same time or interchangeably.
Caution:
Install wiring so that it is not tight and under tension. Wiring under tension
may break, or overheat and burn.

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)
A Screw holding cover (1pc)
2. Open knockout holes
(Recommend to use a screwdriver or the like for this work.)

E Remove
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.
[Fig. 9.3.3] (P.6)
F Use PG bushing to keep the weight of the cable and external force from being
applied to the power supply terminal connector. Use a cable tie to secure the
cable.

K Side frame
M Washer (round) (accessory)
4. Connect the power source, Earth, transmission and remote controller wiring.
The dismounting of the terminal box is not needed.

E Insulation tape (To keep the earth wire of the shielded cable from coming in contact
with the transmission terminal)
5. After wiring is complete, make sure again that there is no slack on the con-
nections, and attach the cover onto the terminal box in the reverse order of
removal.
Notes:
•
Do not pinch the cables or wires when attaching the terminal box cover.
Doing so may cause a risk of disconnection.
•
When accommodating the terminal box, make sure that the connectors on
the box side are not removed. If removed, it cannot operate normally.
9.4. External I/O specifications
Caution:
1. Wiring should be covered by insulation tube with supplementary insula-
tion.
2. Use relays or switches with IEC or equivalent standard.
3. The electric strength between accessible parts and control circuit should
have 2750 V or more.
