Guidance and manufacture’s declaration – electromagnetic immunity
The BM 66/U is intended for use in the electromagnetic environment specified below. The customer or the user of the BM 66/U 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 material, the rela-
tive 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 com-
mercial 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 typical com-
mercial or hospital environment.

ruptions and voltage

ply input lines

Mains power quality should be that of a typical com-
mercial or hospital environment. If the user of the
BM 66/U requires continued operation during power
mains interruptions, it is recommended that the BM
66/U be powered from an uninterruptible power sup-
ply 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 com-
mercial or hospital environment.
NOTE:
U
T
is the a.c. mains voltage prior to application of the test level.
