Notes
(a) Leakage Switch is necessary for additional installation. If circuit breakers with leakage protection are in use,
action response time must be less than 0.1 second, leakage circuit must be 30mA.
(b) The above selected power cable diameters are determined based on assumption of distance from the
distribution cabinet to the unit less than 75m. If cables are laid out in a distance of 75m to 150m, diameter of
power cable must be increased to a further grade.
(c) The power supply must be of rated voltage of the unit and special electrical line for air-conditioning.
(d) All electrical installation shall be carried out by professional technicians in accordance with the local laws
and regulations.
(e) Ensure safe grounding and the grounding wire shall be connected with the special grounding equipment of
the building and must be installed by professional technicians.
(f) The specications of the breaker and power cable listed in the table above are determined based on the
maximum power (maximum amps) of the unit.
(g) The specications of the power cable listed in the table above are applied to the conduit-guarded multi-wire
copper cable (like, YJV XLPE insulated power cable) used at 40
℃
and resistible to 90
℃
(see IEC 60364-5-52).
If the working condition changes, they should be modied according to the related national standard.
(h) The specifications of the breaker listed in the table above are applied to the breaker with the working
temperature at 40
℃
. If the working condition changes, they should be modied according to the related
national standard.
