Electromagnetic
environment - guidance
Floors should be wood,
concrete or ceramic tile. If
floors are covered with
synthetic material, the
relative humidity should be at
least 30%.
Mains power quality should
be that of a typical
commercial or hospital
environment.
Mains power quality should
be that of a typical
commercial or hospital
environment.
Mains power quality should
be that of a typical
commercial or hospital
environment. If the user of
the generator requires
continued operation during
power mains interruptions, it
is recommended that the
system be powered from an
uninterruptible power supply
or a battery.
Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical
commercial or hospital
environment.
