Exposure to high humidity or corrosiveenvironments will prematurely degrade the electroniccomponents in any electronic device regardless of its useor manufacturer, unless specific precautions, such asthose mentioned in the Environment section above, aretaken.NoteIt is recommended that all relays be powered up once per year, for one hourcontinuously, to avoid deterioration of electrolytic capacitors and subsequent relayfailure.
