(3) Preparation of indoor unit
(a) Mounting of connecting wires
1) Remove the lid (R).
2) Remove the terminal cover.
3) Remove the wiring clamp.
4) Connect the connecting wire securely to the terminal block.
Use cables for interconnection wiring to avoid loosening of the
wires.
CENELEC code for cables. Required field cables.
H05 RNR3G1.5 (Example) or 245IEC57
H Harmonized cable type
05 300/500 volts
R Natural-and/or synth, rubber wire insulation
N Polychloroprene rubber conductors insulation
R Standed core
4or5 Number of conductors
G One conductor of the cable is the earth conductor (yellow/
green)

1 Connect the connection wire securely to the terminal block. If the wire is not affixed completely, contact will be
poor,and it is dangerous as the terminal block may heat up and catch fire.
2 Take care not to confuse the terminal numbers for indoor and outdoor connections.
3 Affix the connection wire using the wiring clamp.
5) Fix the connecting wire by wiring clamp.
6) Attach the lid.
7) Close the suction grille.
(b) Protective taping (Protect the cable with tape at the section where the cable passes through the hole opened on the wall.)
