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) and fix
the cable with a tie wrap.
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), and fix the
cable with a tie wrap.
4 Power supply cable: Route the cable through the frame and
connect the cable to the terminal block (L, N, earth).

e For use with 2 user interfaces
▪ Setting master unit (Cooling/Heating masterhood). In case of
group control, connect the user interface wiring directly to the
master unit. Do not connect user interfaces directly to slave units.
Slave units are restricted in their operation by the master unit (e.g.
1 outdoor unit does not allow for 1 indoor unit to run in cooling
operation while another runs in heating operation). For setting
using the user interface, refer to the manual or reference guide of
the user interface.
▪ 2 or more user interfaces: When using 2 or more user
interfaces, one must be
set to "MAIN" and the other to "SUB". For setting procedure see
the installation
and operation manual of the used user interface.
INFORMATION
In case of group control, it is not necessary to assign a
group address to the indoor unit. The group address is
automatically set when the power is turned on.
