EMC INFORMATION
Electromagnetic environment-
guidance
Floors should be wood, concrete
or ceramic tile. If floors are cov-
ered 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 Planmeca ProMax X-ray unit
requires continued operation dur-
ing power mains interruptions, it
is recommended that Planmeca
ProMax X-ray unit be powered
from an uninterruptible power
supply.
Power frequency magnetic fields
should be at levels characteristic
of a typical location in a typical
commercial or hospital environ-
ment. The power frequency mag-
netic field should be measured in
the intended installation location
to assure that it is sufficiently low.
