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(
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 environ-
ment. The power frequency mag-
netic 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.
