Keep the AC motor drive in the shipping carton or crate before installation. In order to retain the warranty
coverage, properly store the AC motor drive when it is not to be used for an extended period of time. The
proper storage conditions are listed below.
Store in a clean and dry location without any direct sunlight or corrosive fumes.
Store in an ambient temperature range between -20°C to +60°C.
Store in a relative humidity range between 0% to 90% and non-condensing
environment.
DO NOT store in the environment with corrosive gas or liquid.
DO NOT place directly on the ground. If the surrounding environment is humid, you
should put a desiccant in the carton or crate.
DO NOT store in an area with rapid changes in temperature that may cause
condensation or frost to form.
If the AC motor drive is stored for more than three months, the temperature should
not be higher than 30°C. Storage for longer than one year is not recommended; it
could result in the degradation of the electrolytic capacitors.
When the AC motor drive is not used for long time after installation in an
environment with humidity and dust, it is the best to move the AC motor drive to a
better environment as stated above.
