Mains power quality should be
that of a typical commercial or
hospital environment. If the
Universal DrillSaw Battery
Charger requires continued
operation during power mains
interruptions, it is recommended
that the Universal DrillSaw
Battery Charger 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
environment.
Note: UT is the AC mains voltage prior to application of the test level.
