FIELD WIRING

Caution

All field wiring and components must be installed by a licensed 
electrician and must comply with relevant local and national 
regulations.

Be sure to use a dedicated power circuit. Never use a power sup-
ply shared by another appliance.

Never install a phase advancing capacitor. As this unit is equipped 
with an inverter, installing a phase advancing capacitor will not 
only deteriorate power factor improvement effect, but also may 
cause capacitor abnormal heating accident due to high-frequency 
waves.

Only proceed with wiring work after blocking off all power.

Always ground wires in accordance with relevant local and 
national regulations.

This machine includes an inverter device. Connect earth and 
leave charge to eliminate the impact on other devices by reducing 
noise generated from the inverter device and to prevent leaked 
current from being charged in the outer hull of the product.

Do not connect the ground wire to gas pipes, sewage pipes, light-
ning rods, or telephone ground wires.

Gas pipes :

 can explode or catch fire if there is a gas leak.

Sewage pipes :

 no grounding effect is possible if hard plastic pip-

ing is used.

Telephone ground wires and lightning rods :

 dangerous when 

struck by lightning due to abnormal rise in electrical potential in 
the grounding.

Be sure to install an earth leakage circuit breaker.
This unit uses an inverter, so install the earth leakage circuit 
breaker that be capable of handling high harmonics in order to 
prevent malfunctioning of the earth leakage circuit breaker itself.

Earth leakage circuit breaker which are especially for protecting 
ground-faults should be used in conjunction with main switch or 
fuse for use with wiring. Make sure that the capacity is the same 
as or more than the rated capacity of the fuse or breaker in that 
case.

Note

Electrical wiring must be done in accordance with the wiring dia-
grams and the description herein.

Do not operate until refrigerant piping work is completed.
(If operated before complete the piping work, the compressor may 
be broken down.)

This product have reversed phase protection detector that only 
works when the power is turned on. If there exists black out or the 
power goes on and off which the product is operating, attach a 
reversed phase protection circuit locally. Running the product in 
reversed phase may break the compressor and other parts.

Attach the power wire securely. Introducing power with a missing 
N-phase or with a mistaken N-phase will break the unit.

Make sure the electrical unbalance ratio is no greater than 2%. If 
it is larger than this, the unit’s lifespan will be reduced.
If the ratio exceeds 4%, the unit will shut down and an malfunction 
code will be displayed on the indoor remote controller.

Never remove thermistor, sensor or etc. when connecting power 
wiring and transmission wiring.
If operated with thermistor, sensor or etc. removed, the compres-
sor may be broken down.

Never connect the power supply in reversed phase. 
The unit can not operate normally in reversed phase.
If you connect in reversed phase, replace two of the three phases.

Connect the wire securely using designated wire and fix it with 
attached clamp without applying external pressure on the termi-
nal parts (terminal for power wiring, terminal for transmission wir-
ing and earth terminal).

7-1 Power circuit, safety device and cable 

requirements

A power circuit (see the following table) must be provided for con-
nection of the unit. This circuit must be protected with the required 
safety devices, i.e. a main switch, a slow blow fuse on each phase 
and an earth leakage circuit breaker.

When using residual current operated circuit breakers, be sure to 
use a high-speed type (0.1 second or less) 200mA rated residual 
operating current.

Specifications for local wiring are in compliance with IEC60245.

Select the power supply cable type and size in accordance with 
relevant local and national regulations.

Use copper conductors only.

Use insulated wire for the power cord.

Use wire type H05VV when protected pipes are used.
Use wire type H07RN-F when protected pipes are not used.

Note

All field wiring is to be procured on site.

Make sure the weak electric wiring (i.e. for the remote controller, 
between units, etc.) and the power wiring do not pass near each 
other, keeping them at least 50 mm apart.
Proximity may cause electrical interference, malfunctions, and 
breakage.

Transmission wiring should be secured as described in “

7-4 

Transmission Wiring Connection Procedure

”.

Be sure to connect the power wiring to the power wiring terminal 
block and secure it as described in “

7-5 Power Wiring Connec-

tion Procedure

”.

Secure wiring with clamp such as insulation lock ties to avoid con-
tact with piping.

Shape the wires to prevent the structure such as the EL. COMPO. 
BOX lid deforming. And close the cover firmly.
