Chapter 1 Introduction
The AC motor drive should be kept in the shipping carton or crate before installation. In order
to retain the warranty coverage, the AC motor drive should be stored properly when it is not to
be used for an extended period of time. Storage conditions are:
CAUTION!
1.
Store in a clean and dry location free from direct sunlight or corrosive fumes.
2.
Store within an ambient temperature range of -20
°
C to +60
°
C.
3.
Store within a relative humidity range of 0% to 90% and non-condensing environment.
4.
Store within an air pressure range of 86 kPA to 106kPA.
5.
DO NOT place on the ground directly. It should be stored properly. Moreover, if the surrounding
environment is humid, you should put exsiccator in the package.
6.
DO NOT store in an area with rapid changes in temperature. It may cause condensation and
frost.
7.
If the AC motor drive is used but did not use more than three months, the temperature should
not be higher than 30 °C. Storage longer than one year is not recommended, it could result in
the degradation of the electrolytic capacitors.
8.
When the AC motor drive is not used for longer time after installation on building sites or places
with humidity and dust, it’s best to move the AC motor drive to an environment as stated above.
9.
If the electrolytic capacitors do not energize for a long time, its performance will decline.
Therefore, the unused drive must be charged 3 ~4 hours every two years (*) to recover the
performance of internal electrolytic capacitor of drive.
*Note
：
It need to use the adjustable AC power source when the inverter power transmission
(eg.: AC autotransformer) and pressurize to the rated voltage gradually, do not do the power
transmission by using rated voltage directly.
