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

It may be necessary
to position the Invia
Ease 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.
NOTE: U
T
is the a.c. mains voltage prior to application of the test level.
