indoor unit
NOTICE
▪ Follow the wiring diagram (delivered with the unit,
located at the inside of the service cover).
▪ For instructions on how to connect the decoration panel
and the sensor kit, see the installation manual delivered
with the panel or the kit.
▪ Make sure the electrical wiring does NOT obstruct
proper reattachment of the service cover.
It is important to keep the power supply and the transmission wiring
separated from each other. In order to avoid any electrical
interference the distance between both wirings should ALWAYS be
at least 50 mm.
NOTICE
Be sure to keep the power line and transmission line apart
from each other. Transmission wiring and power supply
wiring may cross, but may NOT run parallel.
1 Remove the service cover.
2 User interface cable: Route the cable through the frame,
connect the cable to the terminal block, and fix the cable with a
cable tie.
3 Interconnection cable (indoor↔outdoor): Route the cable
through the frame, connect the cable to the terminal block
(make sure the numbers match with the numbers on the
outdoor unit, and connect the earth wire), and fix the cable with
a cable tie.

make contact with electrical parts can cause malfunctions,
smoke or fire.
