level environment – guidance
± 6 kV contact Floors should be wood, concrete or
± 8 kV air ceramic tile. If floors are covered with
synthetic material, the relative humid-
ity should be at least 30%.
± 2 kV Mains power quality should be that of
for power a typical commercial or hospital envi-
supply lines ronment.
± 1 kV
for input /
output lines
± 1 kV Mains power quality should be that of
differential mode a typical commercial or hospital envi-
± 2 kV ronment.
common mode
< 5% UT Mains power quality should be that
(> 95% dip in UT) of a typical commercial or hospital
for 0.5 cycle environment. If the user of Thopaz
requires continued operation during
40% UT power mains interruptions, it is rec-
(60% dip in UT) ommended that Thopaz be powered
for 5 cycles from an uninterruptible power supply
or a battery.
70% UT
(30% dip in UT)
for 25 cycles
< 5% UT
(> 95% dip in UT)
for 5 sec
Power frequency magnetic fields
3 A/m should be at levels of a typical com-
mercial or hospital environment.
