6.1.3 Storing options
6.1.3.1 Temporary storage
Options should be stored in an environment that satisfies the conditions listed in Table 6.1.6.
Table 6.1.6 Storage Environment
Item Specifications
Ambient
temperature
-10 to +50°C
Storage temperature
(Note 1)
-25 to +70°C
Relative humidity 5 to 95% (Note 2)
Avoid use in environments where abrupt changes in temperature
may cause condensation or freezing.
Atmosphere
Avoid exposure to dust, direct sunlight, corrosive gases, flammable gas, oil mist, steam,
water droplets and oscillation. Avoid exposure to excessive salt content.
(Note 1): Storage temperatures assume short-term exposure as during shipment.
(Note 2): Condensation or freezing may occur in locations where there are significant changes in temperature, even if the humidity
satisfies the specifications. Avoid storage in such locations.
(1) Do not place options directly on the floor. Instead, store on a table or shelf.
(2) If the storage environment does not satisfy the conditions listed in Table 6.1.6, wrap the option in a
vinyl sheet, polyethylene film designed for packaging use, or other material.
(3) If exposure to humidity is a concern, place a desiccant (silica gel, etc.) inside the packaging and
then wrap as described in (2) above.
6.1.3.2 Long-term storage
The method used to store options for an extended period of no use after purchase varies greatly with the
storage environment. If the device must be stored under precisely controlled conditions, consult the
company from which you purchased the product or your nearest Fuji sales office with information about
the specific specifications.
Generally speaking, the following storage practices should be observed:
(1) Options should be stored in an environment that meets the temporary storage conditions.
(2) Options should be packaged carefully to prevent the incursion of humidity and foreign matter.
Enclose a desiccant (silica gel, etc.) in the packaging. See JIS Z 0301 (damp-proof packaging
methods) for the quantity of desiccant to use. Aim for a relative humidity of 70% or less inside the
packaging.
When the option is to be installed in the FRENIC-VG and then left unused in a device or control panel for
a period of time, particularly at a location where construction work is being carried out, the device is
likely to be exposed to humidity and dust. In such situations, remove the entire FRENIC-VG inverter and
store it in an environment that satisfies the conditions listed in Table 6.1.6.
