8.10. Electrical wiring work
8.10.1. Preparing the electrical wiring work
A main switch or other means for disconnection, having a
contact separation in all poles, must be incorporated in
the fixed wiring in accordance with the applicable
legislation.
Use only copper wires.
All field wiring must be carried out in accordance with the
wiring diagram supplied with the unit and the instructions
given below.
Never squeeze bundled cables and be sure that it does
not come in contact with the non-insulated piping and
sharp edges. Be sure no external pressure is applied to
the terminal connections.
Power supply wires must be attached securely.
Be sure to use a dedicated power circuit, never use a
power supply shared by another appliance.
If the power supply has a missing or wrong N-phase,
equipment will break down.
Be sure to establish an earth. Do not earth the unit to a
utility pipe, surge absorber, or telephone earth.
Incomplete earth may cause electrical shock.
Be sure to install an earth leakage protector in
accordance with the applicable legislation. Failure to do
so may cause electric shock or fire.
The earth leakage protector must be compatible with the
inverter (resistant to high frequency electric noise) to
avoid unnecessary opening of the earth leakage
protector. A residual current device type A with a
sensitivity of 300 mA will provide adequate protection
level unless local legislation prescribes otherwise.
As this unit is equipped with an inverter, installing a
phase advancing capacitor not only will deteriorate
power factor improvement effect, but also may cause a
capacitor abnormal heating accident due to high-
frequency waves. Therefore, never install a phase
advancing capacitor.
Be sure to install the required fuses or circuit breakers.
Never remove a thermistor, sensor, etc., when
connecting power wiring and transmission wiring.
(If operated without thermistor, sensor, etc., the
compressor may break down.)
The reversed phase protection detector is designed to
stop the product in the event of an abnormality when the
product is started up. Reversed phase detection is not
performed consequently during normal operation of the
product.
If reverse-phase detection occurs replace 2 of the 3
phases (L1, L2, and L3). (Refer to "9.5.2. Error codes" on
page 26).
If there exists the possibility of reversed phase after a
momentary black out and the power goes on and off
while the product is operating, attach a reversed phase
protection circuit locally. Running the product in reversed
phase can break the compressor and other parts.
Point of attention regarding quality of the public electric power
supply.
This equipment complies with respectively:
EN/IEC 61000-3-11
(1)
provided that the system impedance Z
sys
is less then or equal to Z
max
.
EN/IEC 61000-3-12
(2)
provided that the short-circuit power S
sc
is greater than or equal to the minimum S
sc
value
at the interface point between the user's supply and the public
system. It is the responsibility of the installer or user of the equipment
to ensure, by consultation with the distribution network operator if
necessary, that the equipment is connected only to a supply with
respectively:
Z
sys
less than or equal to Z
max
S
sc
greater than or equal to the minimum S
sc
value.
For cable selection refer to "8.10.6. Connection of the unit power
supply and communication cable(s)" on page 15.
For the recommended fuses, see the table below.

WARNING: Electrical installation
All field wiring and components must be installed by an
installer and must comply with the applicable legislation.
DANGER: ELECTRICAL SHOCK
See "4. Precautions for installation" on page 2.
WARNING
(1) European/International Technical Standard setting the limits for voltage
changes, voltage fluctuations and flicker in public low-voltage supply
systems for equipment with rated current ≤75 A.
(2) European/International Technical Standard setting the limits for harmonic
currents produced by equipment connected to public low-voltage systems
with input current >16 A and ≤75 A per phase.
