6. ELECTRICAL WIRING
]
WARNING
• Electrical work must be performed in accordance with this
Manual by a person certi
fi
ed under the national or regional
regulations. Be sure to use a dedicated circuit for the unit.
An insufficient 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 specified by the manufacturer. Improper
connections, insufficient 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,
insuf
fi
cient 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 leakage 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.
• Install a ground leakage breaker. In addition, install the
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 ground cable.
Improper 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.
CAUTION
• Ground the unit.
Do not connect the ground cable to a gas pipe, water
pipe, lightning rod, or a telephone ground cable.
Improper 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 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 a 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.
