• Power supply cords of parts of appliances for outdoor
use shall not be lighter than polychloroprene sheathed
flexible cord. (Code designation IEC:60245 IEC 57 /
CENELEC: H05RN-F)
• Since it has the external power supply, refer to the
outdoor unit installation manual for MAIN POWER.
CAUTION
• When installing the indoor unit in a computer
room or network room, use the double shielded
communication cable (tape aluminum / polyester
braid + copper) of FROHH2R type.
• Select the power cable in accordance with relevant
local and national.
• Wire size must comply with local and national code.
• You should connect the power cable into the power
cable terminal and fasten it with a clamp.
• The unbalanced power must be maintained within 10%
of supply rating among whole indoor units.
• If the power is unbalanced greatly, it may shorten
the life of the condenser. If the unbalanced power
is exceeded by more than 10% of supply rating,
the indoor unit will protect itself by stopping and
displaying an error code.
• Connect the power cable to the auxiliary circuit
breaker. An all pole disconnection from the power
supply must be incorporated in the fixed wiring
[ 0.12inch (3mm)].
• You must keep the cable in a protection tube.
• Maximum length of power cables are decided within
10% of power drop. If it exceeds, you must consider
another power supplying method.
• The circuit breaker (MCCB, ELB) should be considered
more capacity if many indoor units are connected from
one breaker.
• Use round pressure terminal for connections to the
power terminal block.
• For wiring, use the designated power cable and
connect it firmly, then secure to prevent outside
pressure being exerted on the terminal board.
• Use an appropriate screwdriver for tightening the
terminal screws. A screwdriver with a small head will
strip the head and make proper tightening impossible.
• Over-tightening the terminal screws may break them.
