1.4 Storage Environment

1.4.1 Temporary storage

Store the inverter in an environment that satisfies the requirements listed in Table 1.1.

* Even if the humidity is within the specified requirements, avoid such places where the inverter will be
subjected to sudden changes in temperature that will cause condensation to form.
Precautions for temporary storage
(1) Do not leave the inverter directly on the floor.
(2) If the environment does not satisfy the specified requirements, wrap the inverter in an airtight
vinyl sheet or the like for storage.
(3) If the inverter is to be stored in an environment with a high level of humidity, put a drying agent
(such as silica gel) in the airtight package described in item (2).

1.4.2 Long-term storage

The long-term storage methods for the inverter vary largely according to the environment of the
storage site. General storage methods are described below.
(1) The storage site must satisfy the requirements specified for temporary storage.
However, for storage exceeding three months, the ambient temperature should be within the
range from -10 to +30 °C. This is to prevent the electrolytic capacitors in the inverter from
deteriorating.
(2) The inverter must be stored in a package that is airtight to protect it from moisture. Include a
drying agent inside the package to maintain the relative humidity inside the package to within
70%.
(3) If the inverter has been installed in the equipment or control board at a construction site where
it may be subjected to humidity, dust or dirt, then remove the inverter and store it in a suitable
environment.
Precautions for storage over 1 year
If the inverter will not be powered on for a long time, the property of the electrolytic capacitors may
deteriorate. Power the inverters on once a year and keep them on for 30 to 60 minutes. Do not
connect the inverters to motors or run the motor.
