NOTE UT is the a.c. mains voltage prior to application of the test level.
Compliance level Electromagnetic environment – 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 %.
Not applicable Mains power quality should be that of a typical commercial or hospital
environment.
Not applicable Mains power quality should be that of a typical commercial or hospital
environment.
Not applicable Mains power quality should be that of a typical commercial or hospital
environment. If the user of the FT 100 requires continued operation during
power mains interruptions, it is recommended that the FT 100 be powered
from an uninterruptible power supply or a battery.
3 A/m Power frequency magnetic fields should be at levels characteristic of a
typical location in a typical commercial or hospital environment.
