(1) The general specifications of programmable controllers are as follows. Please do not store
spare parts under a high temperature or high humidity condition, even within the range
guaranteed by the specifications.
(2) Store in a place avoiding direct sunlight.
(3) Store under a condition with no dust or corrosive gas.
(4) The capacity of the batteries (such as an A6BAT battery and an A8BAT battery) or a
lithiumcoin battery (commercially available) for memory card is decreased by its self-
discharging even when it is not used. Replace it with new one in 5 years as a guideline.
(5) Among power supply modules or CPU modules with built-in power supply that use any
aluminum electrolytic capacitor, the characteristics of the modules listed below will be
deteriorated if they are left un-energized for a long time. Therefore, take the following
measures.
[Measures for preventing aluminum electrolytic capacitor characteristics deterioration]
Apply the rated voltage to the aluminum electrolytic capacitor for several hours to activate it. Or,
rotate products at the periodic inspection (in every 1 to 2 years).
[Reference]
The life of an aluminum electrolytic capacitor, even if not used and under a normal temperature,
decreases approximately 4 times slowly than the case when it is energized.
