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 90/1 requires continued operation during
power mains interruptions, it is recommended that the FT 90/1 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.
