• Areas of high humidity (if it must be stored in a high humidity place, insulate it from outside and
use a dehumidifier.)
• Areas are prone to temperature extremes; high temperatures of more than 55 °C (131 °F) and
low temperatures of less than -25 °C (-13 °F).
• Areas where corrosive gases may exist
• Areas subjected to water/dampness
• Areas subjected to excessive dust
• Areas with insufficient ventilation
• Areas subjected to strong magnetic and electric fields or radiation
• Areas which will be subjected to direct sunlight
• Areas subjected to mist
• Areas subjected to electric noise and vibration
