WARNING
• Be sure to comply with local regulations/
codes when running the wire from the
outdoor unit to the indoor unit.
(Size of wire and wiring method etc.)
• A lack of electrical capacitance or incorrect
wiring may cause an electric shock or a
fi
re.
• To make sure that the wiring connection
are secure, use designated cables.
• Fix the cables securely so that no external
force applied to the cables may effect the
terminals.
• If wiring connections are incomplete or
cables are not
fi
xed securely, it may cause
a
fi
re.
• Be sure to ground the outdoor unit.
• Incomplete grounding may lead to an
electric shock.
CAUTION
• Use a circuit breaker of a type that is not
tripped by shock waves.
• Incorrect/incomplete wiring will cause
electrical
fi
res or smoke.
• Prepare the power source for exclusive
use with the air conditioner.
• This product can be connected to the main
power.
Fixed wire connections:
A switch that disconnects all poles and
has a contact separation of at least 3 mm
must be incorporated into the
fi
xed wiring.

• Connect the indoor/outdoor connecting cables to the identical terminal
numbers on the terminal block of each unit.
• Incorrect connection may cause a failure.
1. Detach the front panel from the outdoor unit.
2. Remove the cord clamp.
3. Connect the wires for the power source and each indoor unit.
• Connect the connecting cable to the terminal as identi
fi
ed by the matching
numbers on the terminal block of the indoor and the outdoor unit.
4. Fix the wiring connections for the power source and each indoor unit
securely using a cord clamp.
5. Attach the front panel to the outdoor unit.

Grounding
This air conditioner must be grounded without fail.
• Grounding is necessary not only to safeguard against the possibility
of receiving an electric shock but also to absorb both static, which is
generated by high frequencies and held in the surface of the outdoor unit,
and noise since the air conditioner incorporates a frequency conversion
device (called an inverter) in the outdoor unit.
• If the air conditioner is not grounded, users may receive an electric shock
if they touch the surface of the outdoor unit and that unit is charged with
static.
