7. FIELD WIRING
NOTE
• All field wiring and components must be installed by a licensed elec-
trician 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 mal-
functioning 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 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.)
• Never remove thermistor, sensor or etc. when connecting power wir-
ing 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 blackout 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).
• If there exists the possibility of reversed phase, lose phase, momen-
tary blackout or the power goes on and off while the product is oper-
ating, attach a reversed phase protection circuit locally.
Running the product in reversed phase may break the compressor
and other parts.
7-1 Power circuit, safety device and cable
requirements
• A power circuit (see the following table) must be provided for connec-
tion 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.
• Use copper conductors only.
• Use insulated wire for the power cord.
• Select the power supply cable type and size in accordance with rel-
evant local and national regulations.
• Specifications for local wiring power cord and branch wiring are in
compliance with local cord.

7. Indoor unit
NOTE
•
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 2 in. apart.
Proximity may cause electrical interference, malfunctions, and breakage.
• Be sure to connect the power wiring to the power wiring terminal
block and secure it as described in “7-5 Power Wiring Connection
Procedure”.
• Transmission wiring should be secured as described in “7-4 Trans-
mission Wiring Connection Procedure”.
• Secure wiring with clamp such as insulation lock ties to avoid contact
with piping.
• Shape the wires to prevent the structure such as the EL. COMPO.
BOX lid deforming. And close the cover firmly.
• All field wiring is to be procured on site.
7-3 Leading wire Procedure
• The power wiring and ground wiring are passed out from the power
wiring hole on the sides, the front (knock hole) or the bottom frame
(knock hole) .
• The transmission wiring is passed out from the wiring hole (knock
hole) on the front of the unit or from a piping hole.
