ZEISS 2 Requirements | 2.3 Mains Connection
Category Description
I For connection to circuits in which measures are taken to limit transient
over-voltages to an appropriately low level.
Examples: Protected electronic circuits.
II Energy-consuming equipment to be supplied from the fixed installation.
Examples: Appliances, portable tools, and other household and similar
loads. Measurement equipment intended to measure the voltage levels of
these loads must be rated at this overvoltage category.
III In fixed installations and for cases where the reliability and the availability
of the equipment is subject to special requirements.
Examples: Switches in fixed installation and equipment for industrial use
with permanent connection to the fixed installation; measurement equip-
ment intended to measure the voltage levels of these fixed installations
must be rated at this overvoltage category.
IV Used at the origin of the installation.
Examples: Electricity meters and primary overcurrent protection equip-
ment.
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.
