Electrical wiring work must be performed by an electrician qualified by a local power provider according to
the electrical installation technical standards and interior wiring regulations applicable to the installation site.
Be sure to have the electric wiring work done by qualified electrical installer,
and use exclusive circuit.
Power source with insufficient capacity and improper work can cause electric shock and fire.
Use specified wire for electrical wiring, fasten the wiring to the terminal securely,
and hold the cable securely in order not to apply unexpected stress on the terminal.
Loose connections or hold could result in abnormal heat generation or fire.
Arrange the electrical wires in the control box properly to prevent them from
rising. Fit the lid of the services panel property.
Improper fitting may cause abnormal heat and fire.
Use the genuine option parts. And installation should be performed by a
specialist.
If you install the unit by yourself, it could cause water leakage, electric shock and fire.
Turn off the power source during servicing or inspection work.
If the power is supplied during servicing or inspection work, it could cause electric
shock and injury by the operating fan.
Perform earth wiring surely.
Do not connect the earth wiring to the gas pipe, water pipe, lightning rod and telephone earth
wiring. Improper earth could cause unit failure and electric shock due to a short-circuit.
Make sure to install earth leakage breaker on power source line.
(countermeasure thing to high harmonics.)
Absence of breaker could cause electric shock.
Do not use any materials other than a fuse of correct capacity where a fuse
should be used.
Connecting the circuit by wire or copper wire could cause unit failure and fire.
Do not turn off the power source immediately after stopping the operation.
Be sure to wait for more than 5 minutes. Otherwise it could cause water leakage or
breakdown.
Do not control the operation with the circuit breaker.
It could cause fire or water leakage. In addition, the fan may start operation
unexpectedly and it may cause injury.
Do not repair by yourself. And consult with the dealer about repair.
Improper repair may cause water leakage, electric shock or fire.
Consult the dealer or a specialist about removal of the air-conditioner.
Improper installation may cause water leakage, electric shock or fire.
Shut off the power before electrical wiring work.
It could cause electric shock, unit failure and improper running.
Use the circuit breaker of correct capacity. Circuit breaker should be the one
that disconnect all poles under over current.
Using the incorrect one could cause the system failure and fire.
Earth leakage breaker must be installed.
If the earth leakage breaker is not installed, it can cause electric shocks.
Use power source line of correct capacity.
Using incorrect capacity one could cause electric leak, abnormal heat generation and fire.
Read the “SAFETY PRECAUTIONS” carefully first of all and then strictly follow it during the
installation work in order to protect yourself.
The precautionary items mentioned below are distinguished into two levels,
and .
: Wrong installation would cause serious consequences such as injuries or death.
: Wrong installation might cause serious consequences depending on circumstances.
Both mentions the important items to protect your health and safety so strictly follow
them by any means.
The meanings of “Marks” used here are as shown on the right:
Accord with following items. Otherwise, there will be the risks of electric shock and
fire caused by overheating or short-circuit.
①
Install remote control referring to the attached installation manual.
②
Wiring of remote control should use 0.3mm
2
×
2 core wires or cables.
The insulation thickness is 1mm or more. (on-site configuration)
③
Maximum prolongation of remote control wiring is 600 m.
If the prolongation is over 100m, change to the size below.
But, wiring in the remote control case should be under 0.5mm
2
. Change the wire size
outside of the case according to wire connecting. Waterproof treatment is necessary at the
wire connecting section. Be careful about contact failure.

CAUTION
CAUTION
Always do it according to the instruction.
●
Electrical wiring work must be performed by an electlician an qualified by a local power
provider. These wiring specifications are determined on the assumption that the following
instructions are observed:
①
Do not use cords other than copper ones.
Do not use any source line lighter than one specified in parentheses for each type below.
-braided cord (code designation 60245 IEC 51), if allowed in the relevant part 2;
-ordinary tough rubber sheathed cord (code designation 60245 IEC 53);
-flat twin tinsel cord (code designation 60227 IEC 41);
-ordinary polyvinyl chloride sheathed cord (code designation 60227 IEC 53);
②
Connect the power source to the outdoor unit.
③
Pay extra attention so as not to confuse signal line and power source line connection, because an error in their connection can be
burn all the boards at once.
●
Connect ground wires before connecting wires between the indoor and outdoor units and
between indoor units. The ground wires need to be longer than the wires between the indoor
and outdoor units, and protected from undue stress.
●
Do not turn on the power source before completing the work.
●
The ground wires must be connected by the Class D grounding connection.
●
Use the round crimp terminals for connections to the terminal block.
●
Use dedicated branch circuits, avoiding combination with other devices. Otherwise, it could
trip the power source breaker, resulting in secondary accidents.
●
Install the overcurrent and earth leakage breakers (sensitivity current: 30 mA) specified to
respective models.
●
Do not connect indoor and outdoor signal cables to extension cables on the way. If the joint is
wetted with intruding water, it could cause a ground insulation failure or poor connection,
resulting in communication errors. (If it is inevitable to connect cables on the way, make sure
to prevent the water intrusion completely.)
●
When running wires (wires for power source, remote controller, connecting between indoor
and outdoor units, or other) behind the ceiling, protect them using copper or other pipes
against assault by rat, or other.
●
It is up to 3.5 mm
2
the size of power supply cables connected to indoor units. When using cables
of 5.5 mm
2
or larger, provide a dedicated pull box for branching connection to indoor units.
●
If signal and power source cables are connected mistakenly, it could burn down all PCBs.
①
Even if the power source of 220/240/380/415 V is connected mistakenly to A-B signal cable, it is protected at initial occasion only.
②
If the remote control fails to detect the unit No. (address) at 15 minutes after turning the power on, check and repair all signal
cables for misconnection.
③
Cut the jumper wire J10SL1 of burnt PCB, and reconnect connectors CnK (yellow) and CnK1 (white) to CnK2 (black).
④
If any anomaly is found on wires between the A-B terminal block and the PCB, replace them.
●
At the outside of indoor and outdoor units, take care to avoid direct contacts between remote
control and power source cables.
●
In no event connect the power source of 220/240/380/415 V to the remote control terminal
block. It could cause failures.
●
Connections of wiring between units, ground wire and remote control cable
①
When connecting wires between units, ground wire or remote control wire, connect them according to the number of terminals
on the power source terminal block or signal terminal block in the control box. Connect the ground wire to the ground terminal on
the power source terminal block.
②
Make sure to install an earth leakage breaker for the power source. Select a breaker for inverter circuit.
③
When the earth leakage breaker is exclusive for the earth leakage protection, it is necessary to connect also an isolating switch
( Class B fuse) or wiring circuit breaker in series to the earth leakage breaker.
④
Install the isolating switch close to the unit.
●
Connect wires securing by tightening screws firmly. Confirm also no connector or wire (from
terminal) is disconnected in the control box.
●
When installing an auxiliary electric heater, consult the electric heater manual or technical data.
