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 ambient 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.
The UPS is housed in a NEMA-1 enclosure. The enclosure is designed for indoor use only
and is not to be subjected to falling objects or precipitation.

Consult your Liebert sales representative regarding applications in high ambient
temperatures or call 1-800-LIEBERT. Special temperature sensors must be installed at the
factory.
