Note:
① Power cables are copper core cable and copper connectors must be used for power
cable connection.
② 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.
③ 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;
④ Indoor/outdoor supply cable should be H05RN-F or above.
⑤ The power supply must be of rated voltage of the unit and special electrical line for
air-conditioning.
⑥ All electrical installation shall be carried out by professional technicians in
accordance with the local laws and regulations.
⑦ 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.
