Electromagnetic environment -
guidance
Floors should be wood, concrete
or ceramic tile. If floors are
covered with synthetic material,
the relative humidity should be at
least 30%.
Mains power quality should be
that of a typical commercial or
hospital environment.
Mains power quality should be
that of a typical commercial or
hospital environment.
Mains power quality should be
that of a typical commercial or
hospital environment. If the user of
the SAM e.p.s requires continued
operation during power mains
interruptions, it is recommended
that the SAM e.p.s be powered
from an uninterruptible power
supply or a battery.
If incorrect operation occurs, it
may be necessary to position the
SAM e.p.s 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.
