6. ELECTRICAL WIRING

]
WARNING
• Electrical work must be performed in accordance with this
Manual by a person certified 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 fire.
• 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 fire.
• 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 fire.
• 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 fire.
• 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
fire.
• 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 fire through
exposure to dust or water.
• Install sleeves into any holes made in the walls for wiring.
• Install a ground leakage breaker. In addition, install the

more than 10 seconds to discharge static electricity
charged in the body.
• Do not touch terminals of parts and patterns
implemented on PCB.
