Sayfayı YazdırFor wiring, use the prescribed type of cables, connect them securely, making sure
that there are no external forces of the cables applied to the terminal connections.
Improperly connected or secured cables can cause serious accidents such as
overheating the terminals, electric shock, or fi re.
Do not modify the power cables, use extension cables, or use any branches in the
wiring. Improper connections, insufficient insulation, or exceeding the allowable
current can cause electric shock or fi re.
Match the terminal board numbers and connection cable colors with those of the
outdoor unit. Erroneous wiring may cause burning of the electric parts.
Securely connect the connection cables to the terminal board. In addition, secure the
cables with wiring holders. Improper connections, either in the wiring or at the ends of
the wiring, can cause a malfunction, electric shock, or fi re.
Always fasten the outside covering of the connection cable with the cable clamp.
(If the insulator is chafed, electric discharge may occur.)
Securely install the electrical box cover on the unit. An improperly installed electrical
box cover can cause serious accidents such as electric shock or fi re through exposure
to dust or water.
Install sleeves into any holes made in the walls for wiring. Otherwise, a short circuit
could result.
For U.S.A. and Canada :
When installing this system in high humidity locations, install using ground fault
equipment breakers (often referred to in other countries as an ELCB earth leakage
current breaker) to reduce the risk of leaking current which result in electric shock or
potential fi re.
For others:
Install an earth (ground) leakage breaker. In addition, install the earth (ground)
leakage breaker so that the entire AC main power supply is cut off at the same time.
Otherwise, electric shock or fi re could result.
Always connect the earth (ground) cable.
Improper earthing (grounding) work can cause electric shocks.
Install the remote controller cables so as not to be direct touched with your hand.
Perform wiring work in accordance with standards so that the air conditioner can be
operated safely and positively.
Connect the connection cable fi rmly to the terminal board. Imperfect installation may
cause a fi re.
If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualifi ed persons in order to avoid a hazard.
Earth (Ground) the unit.
Do not connect the earth (ground) cable to a gas pipe, water pipe, lightning rod, or a
telephone earth (ground) cable.
Improper earthing (grounding) may cause electric shock.
Do not connect power supply cables to the transmission or remote controller terminals,
as this will damage the product.
Never bundle the power supply cable and transmission cable, remote controller cable
together.
Separate these cable by 1-31/32 in. (50 mm) or more.
Bundling these cables together will cause miss operation or breakdown.
When handling PCB, static electricity charged in the body may cause malfunction of
the PCB. Follow the cautions below:
• Establish an earth (ground) for the indoor and outdoor units and peripheral devices.
• Cut power (breaker) off.
• Touch metal part of the indoor and outdoor units for more than 10 seconds to
discharge static electricity charged in the body.
• Do not touch terminals of parts and patterns implemented on PCB.

Voltage rating
Operating range
• Select the power cable type and size in accordance with relevant local and national
regulations.
• Specifi cations for local wiring power cord and branch wiring are in compliance with local
code.
• Select the correct cable type and size according to the country or region's regulations.
• Max. wire length: Set a length so that the voltage drop is less than 2%. Increase the
wire diameter when the wire length is long.
CAUTION
208/230 V
187 to 253 V
Refer to the table for the breaker specifi cations of each installation condition.
Perform the power crossover wiring within the range of the same refrigerant system. When
the crossover wiring is done, make a connection for indoor unit to satisfy conditions A and
B below.

When the power crossover wiring is done, make it so that the total of the MCA of the con-
nected indoor equipment does not exceed the 15 A.

Breaker capacity
30 mA, 0.1 sec or less
100 mA, 0.1 sec or less
200 mA, 0.1 sec or less
If the number of units of connected indoor unit exceeds the upper limit, either add breakers
or use a breaker with large capacitance.
