Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of Planmeca ProX intraoral X-
ray unit requires continued
operation during power mains
interruptions, it is recommended
that Planmeca ProX intraoral X-
ray unit be powered from an
uninterruptible power supply.
Power frequency(
50/60 Hz)
magnetic field
IEC 61000-4-8
3 A/m 3 A/m
Power frequency magnetic fields
should be at levels characteristic
of a typical location in a typical
commercial or hospital
environment. The power
frequency magnetic field should
be measured in the intended
installation location to assure
that it is sufficiently low.
NOTE U
T
is the a.c. mains voltage prior to application of the test level.
