At temperatures lower than –20°C, the LCD contrast
may be impaired.
LONG-TERM STORAGE
Environment:
In addition to the above environmental
considerations, the relay should be
stored in an environment that is dry, cor-
rosive-free, and not in direct sunlight.
Correct storage:
Prevents premature component failures
caused by environmental factors such as
moisture or corrosive gases. Exposure
to high humidity or corrosive environ-
ments will prematurely degrade the elec-
tronic components in any electronic
device regardless of its use or manufac-
turer, unless specific precautions, such
as those mentioned in the Environmental
section above, are taken.
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.
