Eaton 93E Generation 2 UPS 100-200 kVA
(380/400/415V)
• Ambient temperature range: 0-40°C
• Recommended operating range: 20-25°C
• Maximum relative humidity: 95%, noncondensing
Note:
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.
If ignored, either one of these aspects can create an undesirable microclimate
at the UPS location. If the environment created by this microclimate exceeds
the Eaton 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.
The UPS equipment operating environment must meet the size requirements in
the figures below. The dimensions are in mm(inch) format.
