Storage 
Observe the following points when the inverter is not used immediately after purchase of when not used 
for a 
long period of time. 
1. 
Avoid storing the unit 
in 
places that are hot or humid, of that contain large quantities of dust or metallic 
dust. Store the unit in a well-ventilated location. 
2. For inverters that have a black anti-static cover, do not remove this cover during storage. 
Always 
remove this cover before applying power for the first time after the storage period. 
3. 
When not using the inverter for an extended period of time, 
tum 
the power on at least once every two 
years to restore the main circuit electrolytic capacitor characteristics. Also verify that the inverter 
functions normally. 
Do not 
directly connect a commercial power source to the inverter, but gradually raise the input voltage 
using a variac, etc. (The power must be 
applied for five hours 
or 
more before running a motor.) 
The large-capacity 
electrolytic capacitors used 
in 
this inverter will deteriorate over time if left deenergized. ·
