2.3.2 UPS Requirements
If the site requires a UPS (Uninterruptable Power Supply), please ensure the KVA rating of the UPS
meets the ratings of the Microscope System and all third-party items that may also be connected,
e.g. water chiller, air compressor, sample prep equipment, EDS or WDS, etc.
This will ensure that the complete system will continue to function during a blackout or brownout
long enough to allow the user to save any experiments and data and to shut off the system prop-
erly.
As battery performance deteriorates over time, always overestimate the time (typically 2x) you re-
quire for the UPS to maintain power in a blackout (long mains interruption) or brownout (short
fluctuation of the mains supply) situation. The UPS only serves to bridge the time of a blackout or
brownout until normal mains is restored. Please ensure to switch off the Microscope System be-
fore the batteries run low in a blackout.
In areas where the mains supply is very unstable or not very clean, the most stable mode of UPS is
the online mode, where the UPS constantly generates the output mains supply.

As a guideline, ask the ZEISS service representative about recommendations for data security pol-
icy on ZEISS Systems.
