prevent the wiring terminal from being stressed; if the length of power cord is insufficient or
the power cord is damaged, it is forbidden to connect two power cords together. Please apply
a new power cord that meets the local regulations.
(5) The unit must be equipped with the circuit breaker and the electric leakage protection device.
The circuit breaker should have both magnetic tripping and thermal tripping functions.
(6) It is forbidden to take power from the inside of the unit, which may cause fire hazard.
(7) When wiring on site, please also refer to the circuit diagram attached on the unit. Before all
electrical installations are completed, it is forbidden to put through the power supply (circuit
breaker and electric leakage protection device on the circuit).
