6. ELECTRICAL WIRING

]
WARNING
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 all units.
Use the included connection cables and power cables or ones specified 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 (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.
Install an earth leakage breaker. In addition, install the earth 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 cable is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualifi ed persons in order to avoid a hazard.
