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 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 opening for

cable, connect the cable to the terminal block (symbols P1, P2).

3

Transmission  cable

:  Route  the  cable  through  the  opening  for

cable,  connect  the  cable  to  the  terminal  block  (make  sure  the
symbols  F1,  F2  match  with  the  symbols  on  the  outdoor  unit).
Bundle the transmission 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.
