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, insuf
fi
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.
We suggest installing GFEB breakers or follow local electrical code.
When installing this system, install using ground fault equipment breakers (GFEB) to
reduce the risk of leaking current which result in electric shock or potential
fi
re.
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 quali
fi
ed persons in order to avoid a hazard.
CAUTION
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 2 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 unit for more than 10 seconds to discharge static
electricity charged in the body.
• Do not touch terminals of parts and patterns implemented on PCB.
