General Instruction
The drawing in this user manual is represented the details of the inner
inverter, so, the drawing is described without cover part and circuit breaker.
But, cover and circuit breaker should be mounted before the operation
following to the instruction of user manual.
Turn off the power of inverter when the inverter is not used.
Cleaning
Be sure to operate the inverter under a clean condition.
When cleaning the inverter, be sure to check the inverter is off. Start cleaning

Make sure that you satisfy the recommended storage environment. (See
page v.)
If the storage period exceeds 3 months, be sure to keep it at the ambient
temperature of -10 ~ +30
˚
C to prevent
『
Deterioration by Temperature
』
of
electrolytic condenser.
Be sure to keep it in a proper package to prevent moisture, etc. Put the
desiccant (Silica Gel), etc., in the package so that the relative humidity in the
package can be maintained at 70% or less.
When it is exposed to moisture or dust (mounted on the
『
System
』
or
『
Control Panel
』
, etc. installed at the construction site), remove it and then
keep it under the environmental condition specified in the page v.
Caution
