6. ELECTRICAL WIRING
]
Electrical work must be performed in accordance with this Manual by a person
certifi ed under the national or regional regulations. Be sure to use a dedicated circuit
for the unit. An insuffi cient power supply circuit or improperly performed electrical work
can cause serious accidents such as electric shock or fi re.
Before starting work, check that power is not being supplied to the indoor unit and
outdoor unit.
Use the included connection cables and power cables or ones specifi ed by the
manufacturer. Improper connections, insuffi cient insulation, or exceeding the allowable
current can cause electric shock or fi re.
For 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.
