Mains power quality should be that of a
typical commercial or hospital environment.
If the user of the ATMOS C 21 / C 31
demands continued function even in case
of interruptions of the energy supply, it is
recommended to supply the ATMOS C 21 /
C 31 from an uninterruptible current supply
or a battery.
NOTE U

is the mains alternating current prior to application of the test levels.
