Precautions for the inverter installation environment – Delta
(1) Ambient temperature:
Like other electronic equipment, the inverter has certain requirements for the ambient temperature, which is generally "-10-+40°C". Because the inverter is a high-power electronic equipment, it is very easy to be affected by the working temperature, but in order to ensure the safety of the inverter's work.

The inverter needs to be equipped with a braking resistor-Delta
The inverter is equipped with a braking resistor, mainly to consume part of the energy on the DC bus capacitor through the braking resistor to avoid the voltage of the capacitor being too high. Theoretically, if the capacitor stores a lot of energy, it can be used to release it to drive the motor to avoid energy waste, but the capacity of the capacitor is limited.
