NOTES
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 24-hour period. For operation at higher temperatures, consult
your Liebert sales representative or call Liebert Global Services at 1-800-LIEBERT.
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 1-800-LIEBERT.
