●Electrical wiring work must be performed by an electrician 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 supply 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 Provide a separate power outlet for each outdoor or indoor unit.
③ All indoor units grouped in one system must have power source that can be turned on or off simultaneously.
④ 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 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 supply, remote control, 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 source 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 controller 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 leakag
e breaker is exclusive for the earth leakage protection, it is necessary to connect also an isolating
switch (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.

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.
●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.
●Shut off the power before electrical wiring work.
It could cause electric shock, unit failure and improper running.
●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.
●Earth leakage breaker must be installed.
If the earth leakage breaker is not installed, it can cause electric shocks.
●Make sure to install earth leakage breaker on power source line.
(countermeasure thing to high harmonics.)
Absence of breaker could cause electric shock.
●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.
●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.
●Use power source line of correct capacity.
Using incorrect capacity one could cause electric leak, abnormal heat generation and fire.
●Do not mingle solid cord and stranded cord on power source and signal side
terminal block.
In addition, do not mingle difference capacity solid or stranded cord.
Inappropriate cord setting could cause loosing screw on terminal block, bad electrical contact, smoke 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.

( i ) Necessary sensitivity current ≦ 30
( ii ) 30 < Necessary sensitivity current ≦ 100
(iii) 100 < Necessary sensitivity current
Use a product of rated sensitivity current at 30 mA (0.1 s or less).
Divide the leakage breaker system, in principle, so that the necessary sensitivity
current will become less than 30 mA.
Depending on the situation of installation (according to standards in respective
countries), it may be possible to use a product of rated sensitivity current at 100
mA (0.15 or less).
It is necessary to divide (add) the leakage breaker system.
