CAUTION
The primary power supply capacity is for the air conditioner itself, and does not include
the concurrent use of other devices.
Do not use crossover power supply wiring for the outdoor unit.
If the electrical power is inadequate, contact your electric power company.
Install a breaker (Included with earth leakage circuit breaker) in a location that is not
exposed to high temperatures.
If the temperature surrounding the breaker is too high, the amperage at which the
breaker cuts out may decrease.
Use a breaker (Included with earth leakage circuit breaker) that is capable of handling
high frequencies. Because the outdoor unit is inverter controlled, a high-frequency
earth leakage circuit breaker is necessary to prevent a malfunction of the breaker
itself.
When the electrical switchboard is installed outdoors, place it under lock and key so
that it is not easily accessible.
Never bundle the power supply cable and transmission cable, remote control cable
together. Separate these cable by 50 mm or more. Bundling these cables together will
cause miss operation or breakdown.
Always keep to the maximum length of the transmission cable. Exceeding the maxi-
mum length may lead to erroneous operation.
The static electricity that is charged to the human body can damage the control PC
board when handling the control PC board for address setting, etc.
Please keep caution to the following points.
Provide the grounding of Indoor unit, Outdoor unit and Option equipment.
Cut off the power supply (breaker).
Touch the metal section (such as the unpainted control box section) of the indoor or
outdoor unit for more than 10 seconds. Discharge the static electricity in your body.
Never touch the component terminal or pattern on the PC board.
Knockout hole
6. 2.
CAUTION
Be careful not to deform or scratch the panel while opening the knockout holes.
After opening the knockout hole, remove the burr on the edges to prevent snapping
of cables.
It is recommended to apply rust proof paint on the edges to prevent rust.
Knockout holes are provided for wiring. (Fig. A)
Knockout holes are provided 2 each in the same size in front, lateral and rear sides. (Fig. B)

CAUTION
Caution when wiring cable
•
When stripping off the coating of lead wire, always use the exclusive tool such
as a wire stripper. If there is no exclusive tool available necessarily, carefully
strip the coating by a cutter etc. so that the conductive wire is not damaged.
If it is damaged, it may lead to an open circuit and a communication error.
Pay attention to the following points while attaching wires on the terminal board.
•
Do not attach 2 wires on one side.
Do not twist wires.
Do not cross the wires.
Do not shorted at edge at root.
