|
|
1.This category of electronic equipment is agency rated for use in an atmosphere free of conductive particles. Some industrial facilities may require a room air filtration system to keep the UPS free of excess moisture and contaminants.
2.The UPS system is designed to operate continuously at 40°C. However, design equipment life expectancy will be extended with lower temperatures (25°C is recommended).
3.Ambient temperature is the maximum ambient temperature during any
4.Exercise care during installation to ensure unimpeded airflow through the UPS system. For operation at higher elevations, consult your Liebert sales representative or call Liebert Global Services at
