●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.
●Screw the line to terminal block without any looseness, certainly.
●Do not turn on the switch of power source, before all of line work is done.
●Provide a dedicated branching circuit and never share a branching circuit with other
equipment. If shared, disconnection at the circuit breaker may occur, which can cause
secondary damage.
●Install an over-current and earth leakage breaker (threshold current: 30mA) specified for
each unit without fail.
●Set earth of D-type.
●
Do not connect the power source line [220V/240V/380V/415V] to signal side terminal
block. Otherwise, it could cause failure.
●
Run the lines (power source, remote controller and "between indoor and outdoor unit")
upper ceiling through iron pipe or other tube protection to avoid the damage by mouse
and so on.
●
Connection of a cable beyond 3.5 mm
2
is not permitted. When cables of over 5.5 mm
2
are
in use, provide a dedicated pull box to take a branch to an indoor unit.
●Misconnection between signal wires and power source wires could burn out all PCBs.
Connect them carefully.
① Even if 200 V power source is connected mistakenly to signal wire A or B, PCBs are protected at the first time only.
② If you cannot confirm a unit No. (address) from the remote control 15 minutes after turning the power on, check all signal
wires and correct misconnection(s).
③ Cut off the jumper wire J 10SL1 on the burn-out PCB and replace connectors CnK (yellow) and CnK1 (white) with Cnk2
(black).
④ If there is any anomaly in the wiring from A or B terminal block to the PCB, replace the wiring.
●
Keep "remote control line" and "power source line" away from each other on constructing
of unit outside.
●
Do not add cord in the middle of line (of indoor power source, remote control and signal)
route on outside of unit. If connecting point is flooded, it could cause problem as for electric
or communication.
(In the case that it is necessary to set connecting point on the signal line way, perform
thorough waterproof measurement.)
●Connection of the line ("Between indoor and outdoor unit", Earth and Remote control)
① Remove lid of control box before connect the above lines, and connect the lines to terminal block according to number
pointed on label of terminal block.
I
n addition, pay enough attention to confirm the number to lines, because there is electrical polarity except earth line.
Furthermore, connect earth line to earth position of terminal block of power source.
②
Install earth leakage breaker on power source line. In addition, select the type of breaker for inverter circuit as earth leakage
breaker.
③
If the function of selected earth leakage breaker is only for earth-fault protection, hand switch (switch itself and type "B" fuse) or
circuit breaker is required in series with the earth leakage breaker.
④
Install isolator or disconnect switch on the power supply wiring in accordance with the local codes and regulations.
The isolator should be set in the box with key to prevent touching by another person when servicing.

Note (1) The cord distances are calculated with a voltage drop of 2%. If the distance should exceed the
above data, review the cord thickness to use in accordance with your extension cord regulations.
(2) When total extension of remote control line is more than 100m, change the size of cord
according to "③ Remote Control, Wiring and functions".
In case of Heat recovery 3-pipe systems
Branching controller of heat recovery 3-pipe systems wiring
●When this unit is used as a "Heat Recovery 3-pipe Systems", refer to the installation
manual of a branching control (option).
Control plural indoor units by a single remote control
① A remote control can control plural indoor units (up to 16)
In above setting, all plural indoor units will operate under same mode and temperature setting.
② Connect all indoor units with 2 core remote control line for group control.
③ Use the function of manual address setting to set the indoor and outdoor address number.
○Do not forget to set the number for the outdoor units.
④ As shown in the following figure, the remote control can be used to control multiple outdoor
units.
⑤ One remote control is able to perform group control for multiple units (maximum 16 units).
○Use the rotary SW1 and SW2 provided on the indoor unit PCB (Printed circuit board) to set unique remote control
communication address avoiding duplication.

●
Be sure to have the electrical 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.
●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.
●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.
