(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 condition with less dust or no corrosive gas.
(4) The battery capacity of a A6BAT battery or a lithium-coin battery (commercially
available) for memory card will be decreased by its self-discharging even when not
used. Replace it with new one in 5 years as a guideline.
(5) For a power supply module, CPU module with built-in power supply, or analog module
that use any aluminum electrolytic capacitor, which is indicated in the table below, take
the following measures since the characteristics will be deteriorated when the
aluminum electrolytic capacitor is left un-energized for a long time.
[Countermeasures for preventing aluminum electrolytic capacitor characteristics deterioration]
Apply the rated voltage to the aluminum electrolytic capacitor for several hours once a year to
activate it. Or, rotate products at the periodic inspection (in every 1 year or two).
[Reference]
The life of an aluminum electrolytic capacitor, even if not used, under a normal temperature
decreases approximately at 1/4 speed of the case when it is energized.
