Specifications for field supplied fuses and wire
Allowable length of transmission wiring between indoor and outdoor
units, and between the indoor unit and the remote controller is as

2000 m)
2. Indoor unit - remote controller: max 500 m
WIRING EXAMPLE AND HOW TO SET THE
REMOTE CONTROLLER
How to connect wiring
Remove the switch box cover as shown in figure 12, and make the
connections.
PRECAUTIONS
1 Observe the notes mentioned below when wiring to the power
supply terminal board.
- Use a round crimp-style terminal for insulation sleeve for
connection to the terminal block for wiring the units. When
none are available, follow the instructions below.
- Do not connect wires of different gauge to the same power
supply terminal. (Looseness in the connection may cause
overheating.)
- When connecting wires of the same gauge, connect them
according to the figure.
Use the specified electric wire. Connect the wire securely to the
terminal. Lock the wire down without applying excessive force to
the terminal. Use torques according to the table below.
- When attaching the control box lid, make sure not to pinch
any wires.
- After all wiring connections are done, fill in any gaps in the
casing wiring holes with putty or insulation material (field
supply) thus to prevent small animals or dirt from entering the
unit from outside and causing short circuits in the control box.
2 Keep total current of crossover wiring between indoor units less
than 12 A. Branch the line outside the terminal board of the unit
in accordance with electrical equipment standards, when using
two power wiring of a gauge greater than 2 mm
2
(Ø1.6).
The branch must be sheathed in order to provide an equal or
greater degree of insulation as power supply wiring itself.
3 Do not connect wires of different gauge to the same grounding
terminal. Looseness in the connection may deteriorate the
protection.
4 Remote controller cords and wires connecting the units should
be located at least 50 mm away from power supply wiring. Not
following this guideline may result in malfunction due to
electrical noise.
5 For the remote controller wiring, refer to the "Installation manual
of the remote controller" supplied with the remote controller.
6 Never connect the power supply wiring to the terminal board for
transmission wiring. This mistake could damage the entire
system.
7 Use only specified wires and tightly connect wires to the
terminals. Be careful that wires do not place external stress on
the terminals. Keep wiring in neat order so that they do not
obstruct other equipment such as popping open the switch box
cover. Make sure the cover closes tight. Incomplete connections
could result in overheating, and in the worse case, electric shock
or fire.
