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 insuf
fi
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 all units.
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, 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 (or RB 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.
