Mains power quality
should be that of a
typical commercial or
hospital environment.
If the user of the
breast pump requires
continued operation
during power mains
interruptions, it is
recommended that
the breast pump be
powered from an
uninterruptible power
supply or a battery.
It may be necessary
to position the breast
pump further from
sources of power
frequency magnetic
fields or to install
magnetic shielding.
The power frequency
magnetic field should
be measured in the
intended installation
location to assure that
it is sufficiently low.
