Mains power quality should be that of a
typical
commercial
or
hospital
environment. If the user of the EDR
7800 requires continued
operation
during
power
mains
interruptions, it is recommended that the
EDR 7800 be powered from an
uninterruptible power supply
or a battery.

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.
NOTE UT is the a.c. mains voltage prior to application of the test level.
