5.3.2 To connect the electrical wiring on the
indoor unit
NOTICE
▪ Follow the wiring diagram (delivered with the unit,
located on the switch box cover).
▪ 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.
4 Divide the small sealing (accessory) and wrap it around the
cables to prevent water from entering the unit. Seal all gaps to
prevent small animals from entering the system.
WARNING
Provide adequate measures to prevent that the unit can be
used as a shelter by small animals. Small animals that
make contact with electrical parts can cause malfunctions,
smoke or fire.
5 Reattach the service cover.
