Guidance and manufacturer’s declaration – electromagnetic immunity
The SBM 45 is intended for use in the electromagnetic environment specified below. The customer or the user of the SBM 45 should
assure that it is used in such an environment.
IMMuNITY test
IEC 60601 test level
Compliance level
Electromagnetic environment – guidance
Electrostatic discharge (ESD)
IEC 61000-4-2
± 6 kV contact
± 8 kV air
± 6 kV contact
± 8 kV air
Floors should be wood, concrete or cera-
mic tile. If floors are covered with synthetic
material, the relative humidity should be at
least 30 %.
Electrical fast transient/burst
IEC 61000-4-4
± 2 kV for power supply lines
± 1 kV for input/output lines
± 2 kV for power supply lines Mains power quality should be that of a typi-
cal commercial or hospital environment.
Surge
IEC 61000-4-5
± 1 kV line(s) to line(s)
± 2 kV line(s) to earth
± 1 kV line(s) to line(s)
± 2 kV line(s) to earth
Mains power quality should be that of a typi-
cal commercial or hospital environment.

tions and voltage variations

Mains power quality should be that of a typi-
cal commercial or hospital environment. If
the user of the SBM 45 requires continued
operation during power mains interruptions,
it is recommended that the SBM 45 be pow-
ered from an uninterruptible power supply
or a battery.
Power frequency
(50/60 Hz)
magnetic field
IEC 61000-4-8
3 A/m
3 A/m
Power frequency magnetic fields should be
at levels characteristic of a typical location
in a typical commercial or hospital environ-
ment.
NOTE:
U
T
is the a.c. mains voltage prior to application of the test level.
