Make sure that the environment for the 9395 UPS meets the following operating restrictions:
The environmental requirements specified below are for the air at the intake ports of the 9395, and are the
maximum, not to exceed, ratings.
• Use temperature: -0 °C to +40 °C (32 °F to 104 °F).
Restriction Always maintain a non-condensing environment
• There shall be at least a 1.8° F (1.0° C) difference between the dry bulb temperature and the wet bulb
temperature, at all times, to maintain a non-condensing environment.
• The maximum rate of temperature change shall be limited to 3° F over 5 minutes (36° F/hour), based on
the ASHRAE Standard 90.1-2013.
Cautions regarding UPS operating environmental conditions:
The newer, more energy efficient data center cooling methods (such as air side economization) can create
much wider ranges of temperature and Relative Humidity (RH) in the UPS room and/or data center.
There are two aspects of this increased operating environment that can, if ignored, create issues:
• One is the creation of microclimates, which are persistent variations of temperature and/or RH within a
single room; for example one side of the room is always cooler than the other side, no matter what the
actual temperature is.
• The other aspect is the rate of change of temperature and/or RH, which can occur during transitions within
the cooling system. Examples: changing the mixture ratio of inside versus outside air, or external changes
in 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 the
environment created by this microclimate exceeds the UPS operating specification, the UPS reliability, over
time, will be reduced. These same environmental extremes will also create reliability concerns for any servers
that are exposed to them.
Do not expose the UPS for overly aggressive environments ANSI/ISA-71.04-2013 classifications). Refer to
Table 1 for gas concentration limits. If the UPS is used in a more aggressive environment, it can cause reduced
product life and possibly early failure. If the installation location does not meet the recommended environment,
contact Eaton service representative for further information.

The UPS system installation must meet the following guidelines:
• The system must be installed on a level floor suitable for computer or electronic equipment.
