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.

(i) A circuit breaker must be added to the fixed line. The circuit breaker is all-pole disconnected and the
breaking distance of the contact is at least 3mm.
