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.
