3.1 Environment
The environment will directly affect the proper operation and the life span of the inverter. To ensure
that the inverter will give maximum service life, please comply with the following environmental
conditions:
Protection
Protection Class
IP20, NEMA/UL Open Type
Operating
Temperature
Ambient Temperature: (-10°C - +40°C (14 -104 °F)
With fan: -10°C - +50°C (14-122 °F)
If several inverters are placed in the same control panel, provide a heat
removal means to maintain ambient temperatures below 40°C
Storage
