7. 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 supply 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, lightning 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 piping 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.
Electrical wiring must be done in accordance with the wiring diagrams 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.)
Never remove thermistor, sensor or etc. when connecting power wiring and transmission wiring.
(If operated with thermistor, sensor or etc. removed, 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.
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.
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.
Connect the wire securely using designated wire and fix it with attached clamp without applying external pressure
on the terminal parts (terminal for power wiring, terminal for transmission wiring and earth terminal).
7.1 Power Circuit, Safety Device, and Cable Requirements
A power circuit (see the following table) must be provided for connection 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 (1 second or less)
200mA rated residual operating current.
Use copper conductors only.
Use insulated wire for the power cord.
Select the power supply cable type and size in accordance with relevant local and national regulations.
Specifications for local wiring are in compliance with IEC60245.
Use wire type H05VV when protected pipes are used.
Use wire type H07RN-F when protected pipes are not used.
