2. IMPORTANT INFORMATION
All electrical work should be carried out by a competent person and wiring
must be in accordance with the national electrical installation regulations.
Ensure that installation work is done correctly using the information
contained in this manual.
Make all connections securely so that any outside forces acting on the
cables are not applied to the terminals.
Never modify or repair by yourself.
Any attempt to do so will void the warranty.
To dispose of this product, consult your dealer.
WARNING
1. Using the specified wires, ensure to connect the wires,
and fix wires securely so that the external tension to the
wires do not affect the connecting part of the terminals.
Incomplete connection or fixation may cause a fire, etc.
2. Be sure to connect earth wire. (grounding work)
Incomplete grounding cause an electric shock. Do not
connect ground wires to gas pipes, water pipes, lightning rods
or ground wires for telephone wires.
3. Appliance shall be installed in accordance with
national wiring regulations.
Capacity shortage of power circuit or incomplete
installation may cause an electric shock or a fire.
CAUTION
If incorrect/incomplete wiring is carried out, it will cause an
electrical fire or smoke.
Be sure to install an earth leakage breaker that is not
tripped by shock waves.
If an earth leakage breaker is not installed, an electric shock
may be caused.
Be sure to use the cord clamps attached to the product.
Do not damage or scratch the conductive core and inner
insulator of power and inter-connecting wires when peeling
them.
Use the power cord and Inter-connecting wire of specified
thickness, type, and protective devices required.
Never connect 220-240V power to the terminal blocks (A, B,
U1/U2, U3/U4 etc.) for control wiring (Otherwise, the system
will fail).
REQUIREMENT
For power supply wiring, strictly conform to the Local
Regulation in each country.
For wiring of power supply of the outdoor units, follow the
Installation Manual of each outdoor unit.
Perform the electric wiring so that it does not come to
contact with the high-temperature part of the pipe. The
coating may melt resulting in an accident.
After connecting wires to the terminal blocks, provide a trap
and fix wires with the cord clamp.
Run the refrigerant piping line and control wiring line in
the same line.
Do not turn on the power of the indoor unit until vacuuming
of the refrigerant pipes completes.
Power supply wire and
communication wires specifications
Power supply wire and communication wires are procured
locally.
For the power supply specifications, follow to the table
below. If capacity is little, it is dangerous because overheat
or seizure may be caused. For specifications of the power
capacity of the outdoor unit and the power supply wires,
refer to the Installation Manual attached to the outdoor unit.
Indoor unit power supply
For the power supply of the indoor unit, prepare the
exclusive power supply separated from that of the outdoor
unit.
Arrange the power supply, earth leakage breaker, and
main switch of the indoor unit connected to the same
outdoor unit so that they are commonly used.
Power supply wire specification: Cable 3-core 2.5mm2, in
conformity with Design 60245 IEC 57.
Power supply
Power supply 220-240V —, 50Hz
Power supply switch/Earth leakage breaker or powersupply
wiring/fuse rating for indoor units should be selected by the
accumulated total current values of the indoor units
Power supply wiring Below 50m 2.5 mm2
Control wiring, Central controller wiring
2-core with polarity wires are used for the Control wiring
between indoor unit and outdoor unit and Central controller
wiring.
To prevent noise trouble, use 2-core shield wire,
The length of the communication line means the total
length of the inter-unit wire length between indoor and
outdoor units added with the central control system wire
length
