NOTE
Thiscategory of electronicequipment is agency rated for use inan atmosphere free of
conductiveparticles. Some industrial facilitiesmay require a room air filtration
systemto keep the UPS free of excess moisture and contaminants.
TheUPS system is designed to operate continuously at 40°C. However,design
equipmentlife expectancy will be extended with lowertemperatures (25°C is
recommended).
