• If a terminal is over tightened, it may be damaged.
Refer to the table shown below for tightening torque of terminals.
• Do not carry out soldering finish when stranded wiring are used.
•
Power supply wiring, earth wiring
Remove the control box lid, match the symbol to that of the
power supply terminal block (X2M) and connect the wiring.
Connect the earth wiring also to the power supply terminal
block (X2M). Then, lead the wiring into the indoor unit
through the hole bored on the cover for penetrating piping
according to the section “
6. REFRIGERANT PIPING WORK
”
and bind the wiring with the clamp (4).
•
Remote controller wiring, transmission wiring.
Connect the remote controller wiring to [P1 · P2] and the trans-
mission wiring to [F1 · F2] of the terminal block (X1M) for
remote controller and transmission wiring. Bind the remote
controller wiring and the transmission wiring with the clamp (4).
•
Sticking non woven fabric (15).
To prevent wiring from floating, stick non woven fabric (15).
CAUTION
• Never connect the power supply wiring to the terminal
block for remote controller/transmission wiring (X1M).
It may damage the total system.
• Do not connect the remote controller/transmission wiring
to the wrong terminal block.
