Examples: changing the mixture ratio of inside versus outside air, or external changesin the outside air when going from nighttime into day, and back to night.When ignored, either one of these aspects can create an undesirable microclimate at the UPS location. If theenvironment created by this microclimate exceeds the UPS operating specification, the UPS reliability, overtime, will be reduced. These same environmental extremes will also create reliability concerns for any serversthat are exposed to them.Do not expose the UPS for overly aggressive environments ANSI/ISA-71.04-2013 classifications). Refer toTable 1 for gas concentration limits. If the UPS is used in a more aggressive environment, it can cause reducedproduct life and possibly early failure. If the installation location does not meet the recommended environment,contact Eaton service representative for further information.33..22..33 IInnssttaallllaattiioonn CCoonnssiiddeerraattiioonnssThe UPS system installation must meet the following guidelines:• The system must be installed on a level floor suitable for computer or electronic equipment.UPS Installation Plan and Unpacking
