For the Communication Adaptor control wires, use only two-conductor shielded wire with a cross-section between 0.5 and 2.0 mm2
(MVVS or CPEVS).
Be sure to ground only one end of the shielding.
The overall length of each line should be 1 km or less.
Do not run the communication line through the same conduit as the power supply, use the same cable as the power supply, or run close to
the power supply line (maintain at least 30 cm separation).
Do not run the LINK1 and LINK2 signal lines through the same conduit, use the same cable for wiring, or run them close together.
Use different communication and power cables so they can be differentiated visually.

Wiring procedure
Inter-unit control wiring
Use the shielded wire for inter-unit
control wiring.
Connect terminals 0 and 1 (LINK1) on
the Communication Adaptor signal
terminal strip CN2 to the inter-unit
control wiring terminals of the indoor
or outdoor unit. There is no polarity.
If connecting two inter-unit control
wiring systems, connect terminals 3
and 4 (LINK2) on CN2 in the same
manner.
Communication Adaptor control wire
Connect terminals 11 and 12 (ADAPT
+ and -) on the Communication
Adaptor signal line terminal strip CN2
with the same terminals on the other
Communication Adaptor. The
terminals have polarity. Connect so
the positive and negative elements are
correct.
When connecting, be sure to use
crossover wiring, not a branching
configuration.
3 Precautions for the Communication Adaptor control wire

How to Install the Remote Sensor
NOTE
• Do not twist the remote sensor wiring with the power wiring or run it in the same metal conduit, because this may
cause malfunction.
• Install the remote sensor away from sources of electrical noise.
• Install a noise filter or take other appropriate action if electrical noise affects the power supply circuit of the unit.
Use an electric junction box (field supply) (Fig. 3-85) for flush mounting of the remote sensor.
When mounting the back case to the electric junction box, tighten the screws securely until the screw heads touch the back
case. Otherwise, a loose screw head may damage the PCB on the back of the top cover when mounting the top cover. But do
not over-tighten the screws. Overtightening may deform the back case and cause the unit to fall.

Use the 2 supplied M4 machine screws to secure the remote sensor back case. Prior to mounting,
clear the cutouts in the back case corresponding to the holes in the electric junction box using a screwdriver or the like. Use the spacers and take care not to tighten the screws excessively. If the back case
will not seat well, cut the spacers to a suitable thickness.
3.
Connect field supplied 2 core lead wires to the lead wires from the remote sensor. (See “How to wire
the remote sensor.”)
When connecting the field supplied 2 core lead wires to the terminal block, check the terminal
numbers in the indoor unit to make sure that the wires are correctly connected. (Fig. 3-87) (The
remote sensor is damaged if 220 / 240V AC is applied.)
