7. FIELD WIRING
Caution
All field wiring and components must be installed by a licensed
electrician and must comply with relevant local and national reg-
ulations.
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.
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.)
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.)
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 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 (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.
Note
The above table indicates power specifications for standard combi-
nations (see 2. INTRODUCTION).
If using anything other than the above combinations in a multi sys-
tem, calculate using the following procedure.
Minimum circuit amp value: add the minimum circuit amp values
for each independent unit
Recommended fuse capacity: select the fuse capacity with the next
higher value of the calculated minimum circuit amp. multiplied by 1.1.
Ex: Combining the RXYQ30PTLK(E) using RXYQ8PTLK(E),
RXYQ10PTLK(E), and RXYQ12PTLK(E).
Minimum circuit amp. of the RXYQ8PTLK(E) in table above = 32.7 A
Minimum circuit amp. of RXYQ10PTLK(E) in table above = 41.6 A
Minimum circuit amp. of RXYQ12PTLK(E) in table above = 41.6 A
Accordingly, the minimum circuit amp. of the RXYQ30PTLK(E)
= 32.7 + 41.6 + 41.6= 115.9 A
Multiplying the result above by 1.1 (115.9 × 1.1) = 127.5 A, so the
recommended fuse capacity would be 130 A.

Note
Make sure the weak electric wiring (i.e. for the remote control-
ler, 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.
Be sure to connect the power wiring to the power wiring termi-
nal block and secure it as described in “7-5 Power Wiring
Connection Procedure”.
