Notes
①
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.
②
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.
③
The power supply must be of rated voltage of the unit and special electrical line for
air-conditioning.
④
All electrical installation shall be carried out by professional technicians in accordance with the
local laws and regulations.
⑤
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.
⑥
The specifications of the breaker and power cable listed in the table above are determined
based on the maximum power (maximum amps) of the unit.
⑦
The specifications 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°C
and resistible to 90°C (see IEC 60364-5-52). If the working condition changes, they should be
modified according to the related national standard.
⑧
The specifications of the breaker listed in the table above are applied to the breaker with the
working temperature at 40°C. If the working condition changes, they should be modified
according to the related national standard.
