Normal use, installation and transportation, storage conditions
2.1 Conditions of use, transportation and storage
1. Use the ambient temperature (-10~＋45)°C, derate use between 45°C~55°C, derate use by 1% for every
1°C increase in temperature;
2. Relative humidity (5~95)% RH;
3. Storage temperature -25°C~ + 55°C ,
4. If the altitude is above 1000 meters, please derate at the rate of 1 % for every 100m increase , but not
more than 3000m;
5. Indoors , without direct sunlight, without dust, corrosive gas, flammable gas, oil mist, water vapor,
dripping water or salt,

6. (2~9)Hz amplitude ≤ 0.3mm, (9- 200)Hz vibration acceleration ≤5.8m/ s ;
note： Inverters stored for a long time must undergo a power-on test within 2 years. When powering on, use a voltage
regulator to slowly increase to the rated value, and power on for 1 hour without load, otherwise there is a risk
of electric shock and explosion.
2.2 Installation conditions
When using the inverter, please pay attention to the installation spacing and distance requirements, as
shown in Figure 2.1 :
