It is recommended that all relays be powered up once per year, for one hour continuously,
to avoid deterioration of electrolytic capacitors and subsequent relay failure.

In addition to the above environmental considerations, the
relay should be stored in an environment that is dry, corrosive-
free, and not in direct sunlight.
Prevents premature component failures caused by
environmental factors such as moisture or corrosive gases.
Exposure to high humidity or corrosive environments will
prematurely degrade the electronic components in any
electronic device regardless of its use or manufacturer, unless
specific precautions, such as those mentioned in the
Environmental section above, are taken.
