Do not place the UPS near a source of dust or sand. Excessive amount of
dust or sand can cause damage or lead to malfunction.

Observe caution regarding UPS operating environmental conditions. The newer,
more energy efficient data center cooling methods (such as air side economizing)
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:

•

The creation of micro climates, 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 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 night time into day, and back to night.

When ignored, either one of these aspects can create an undesirable micro
climate at the UPS location. If the environment created by this micro climate
exceeds the UPS operating specification, the UPS reliability is reduced over time.
These same environmental extremes create also reliability concerns for any
servers that are exposed to them.

4.4.2

Installation considerations

The UPS system installation requires a TN, TT or IT power distribution system
(the IT distribution system shall include a neutral wire).

The UPS system installation must meet the following guidelines:

•

The system must be installed on a level floor suitable for computer or
electronic equipment. The floor must be suitable for heavy weight and
wheeling.

•

The system must be installed in a temperature and humidity controlled indoor
area that is free of conductive contaminants.

•

The cabinet can be installed in line-up-and-match or standalone
configurations.

If you do not obey these guidelines your warranty may become void.

CAUTION

Do not stack anything on top of the UPS cabinet.

Do not stack the UPS 91PS/93PS C-model cabinet on top of any other
similar cabinet(s).

If installed on a shelf, use suitable supports to prevent the UPS from
tipping or dropping.
