2 Specifications
2.1 Storage Environment
2.1.1 Temporary
Storage
Store the option card in an environment that satisfies the requirements listed in Table 2.1.
Table 2.1 Environmental Requirements for Storage and Transportation
Item Requirements

Relative
humidity
5 to 95%
*2
Location where the option card is not subject to abrupt changes in
temperature that would result in the formation of condensation or ice.
Atmosphere
The inverter must not be exposed to dust, direct sunlight, corrosive or flammable gases, oil mist,
vapor, water drops or vibration. The atmosphere must contain only a low level of salt.

*1
Assuming a comparatively short storage period (e.g., during transportation or the like)
*2
Even if the humidity is within the specified requirements, avoid such places where the option card 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 option card in an airtight vinyl sheet or the like
for storage.
(3) If the option card 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).
2.1.2 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.
(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 option card 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 option card and store it in a suitable environment specified in Table 2.1.
