Level Guidance
± 6 kV contact Floors should be wood, concrete, or
ceramic tile. If floors are covered with
± 8 kV air synthetic material, the relative humidity
should be at least 30%.
±2 kV for power Mains power quality should be that of a
supply lines typical commercial or hospital
environment.
Not applicable
±1 kV Mains power quality should be that of a
differential typical commercial or hospital
mode environment.
±2 kV common
mode
>95% dip in 0.5 Mains power quality should be that of a
cycle typical commercial or hospital
environment. If the user of the ProXenon
60% dip in 5 Headlight Camera System requires
cycles continued operation during power mains
interruptions, it is recommended that the
30% dip for 25 ProXenon Headlight Camera System be
cycles powered from an uninterruptible power
supply or battery.
>95% dip in 5
seconds
3 A/m Power frequency magnetic fields should
be at levels characteristic of a typical
location in a typical commercial or hospital
environment.
