Temporary storage precautions
(1) Do not leave directly on the floor.
(2) If the atmosphere does not satisfy the storage environment in Table1.2-1, store the product after
sealing and packaging it with a plastic sheet.
(3) When there is a risk of the WSU-ST1 being adversely affected by moisture, place desiccant (silica
gel, etc.) inside the product, and then seal and package with a plastic sheet.
Long-term storage
If not using the product for a long period of time following purchase, store in the following condition.
(1) Ensure that the temporary storage environmental conditions are satisfied.
However, if the storage period is 3 months or longer, ensure an ambient temperature of between
-10 and +30 °C to prevent electrolytic capacitor deterioration due to temperature.
(2) Package very carefully to prevent the intrusion of moisture, etc. Fill the packaging with desiccant
(silica gel, etc.), and ensure a relative humidity inside the packaging of 70% or less.
(3) If left in environments exposed to moisture or dust (if installed in equipment or cabinets, etc.
installed in workplaces in which construction work is being carried out), first remove, and then store
in the environment indicated in Table1.2-1.
