The electrical wiring should be applied by the qualied person.
(2) The recommended electrical characteristics are calculated by the related safety standards. The environment temperature is
less than 40°C, the length of the power supply wire is no more than 15 meters. If the air conditioning is in an extreme
environment, please calculate the electrical characteristics again.
(3) If the distribution box or pull box is adopted to the power supply for air conditioning, the size of the power supply wire should be
chosen according to the following table.
