Guidance and manufacturer’s declaration – electromagnetic immunity
The BM 65 is intended for use in the electromagnetic environment specified below. The customer or the user of the BM 65 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 ceramic
tile. If floors are covered with synthetic mate-
rial, 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
± 1 kV for input/output lines
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 typi-
cal commercial or hospital environment. If
the user of the BM 65 requires continued
operation during power mains interruptions,
it is recommended that the BM 65 be powe-
red 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 environment.
NOTE: U T is the a.c. mains voltage prior to application of the test level.
