Environment

Use environments

Indoor, altitude: 1000m (Max.), not exposed to direct sunlight, corrosive gas,

 

 

 

Relative humidity

20 to 93% (free from condensation and vapor).

 

 

 

 

 

explosive gas or vibration (less than 5.9m/s2) (10 to 55Hz).

 

 

 

 

Ambient temperature

-10 to 50°C Note)1.2.3

 

 

 

 

Storage temperature

-20 to +65°C

 

 

 

 

 

 

 

 

 

Note)1. Above 40°C: Remove the protective seal from the top of VF-nC1.

Note)2. When installing inverters side by side (without allowing space between them), detach the label on the top surface of each inverter and use them where the ambient temperature is below 40°C.

Note)3. Single-phase 200V models (built-in EMI noise filter) should be used where the ambient temperature will not rise above 40°C.
