Electromagnetic Environment
- Guidance
Portable and mobile communications
equipment should be separated from the
ATMOS Varioair 3 incl. the cables by no
less than the distances calculated/listed
below.
Recommended distances:
d = [ 1,2] √P
d = [ 1,2] √P
d = [ 2,3] √P
where „P" is the max. power in watts (W)
and D is the recommended separation
distance in meters (m).
Field strengths from fixed transmitters, as
determined by an electromagnetic site (a)
survey, should be less than the compli-
ance level (b).
Interference may occur in the vicinity of
equipment containing following symbol.
Electromagnetic Environ-
ment - Guidance
Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the Vari-
oair 3 demands continued function
even in case of interruptions of the
energy supply, it is recommended
to supply the
ATMOS Varioair 3 from an
uninterruptible current supply or a
battery.
