14.2 To connect the electrical wiring to
the 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 optional
equipment, see the installation manual delivered with
the optional equipment.
▪ Make sure the electrical wiring does NOT obstruct
proper reattachment of the service cover.
It is important to keep the power supply and the interconnection
wiring separated from each other. In order to avoid any electrical
interference the distance between both wirings should ALWAYS be
at least 50mm.
NOTICE
Be sure to keep the power line and interconnection line
apart from each other. Interconnection 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 (symbols P1, P2).
3 Interconnection cable: Route the cable through the frame,
connect the cable to the terminal block (make sure the symbols
F1, F2 match with the symbols on the outdoor unit). Bundle the
interconnection cable with the user interface cable and fix them
with a tie wrap on the wiring fixture.
4 Power supply cable: Route the cable through the frame and
connect the cable to the terminal block (L, N, earth). Fix the
cable with a tie wrap on the wiring fixture.
