Point of attention regarding quality of the public electric power

supply

This equipment complies with respectively:

 EN/IEC 61000-3-11

(4)

provided that the system impedance Z

sys

is less than or equal to Z

max

 EN/IEC 61000-3-12

(5)

provided that the short-circuit power S

is greater than or equal to the minimum S

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

greater than or equal to the minimum S

value.

WARNING

 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.

 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.

 Be sure to use a dedicated power circuit, never use a

power supply shared by another appliance.

 When installing the earth leakage protector be sure

that it is compatible with the inverter (resistant to high

frequency electric noise) to avoid unnecessary

opening of the earth leakage protector.

 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.

 Do not operate until refrigerant piping work is

completed. (If operated before completion of the

piping work, the compressor may break down.)

 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 of this

product only functions when the product starts up.

Consequently reversed phase detection is not

performed during normal operation of the product.

 The reversed phase protection detector is designed to

stop the product in the event of an abnormality when

the product is started up.

 Replace two of the three phases (L1, L2, and L3)

during reverse-phase protection abnormality.

 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.

(4) 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.

(5) 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.
