Indicator

Lamps indicating the inverter status by lighting, such as RUN lamp, MON lamp, PRG lamp, % lamp, Hz lamp,

 

 

 

 

 

frequency setting potentiometer lamp, UP/DOWN key lamp and RUN key lamp. The charge lamp indicates that the

 

 

 

 

 

main circuit capacitors are electrically charged.

 

 

 

 

Environments

Use environments

Indoor, altitude:

1000m (Max.), not exposed to direct sunlight, corrosive gas, explosive gas or vibration (less than

 

 

 

 

Relative humidity

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

 

 

 

 

 

 

 

5.9m/s2) (10 to 55Hz)

 

 

 

 

 

Ambient temperature

-10 to +60°C Note)1.2.

 

 

 

 

 

Storage temperature

-20 to +65°C

 

 

 

 

 

 

 

 

 

 

Note 1. Above 40°C : Remove the protective seal from the top of VF-S11.

If the ambient temperature is above 50°C: Remove the seal from the top of the inverter and use the inverter with the rated output current reduced.

Note 2. If inverters are installed side by side (with no sufficient space left between them): Remove the seal from the top of each inverter.

When installing the inverter where the ambient temperature will rise above 40°C, remove the seal from the top of the inverter and use the inverter with the rated output current reduced.
