Table 2

Guidance and manufacturer’s declaration – electromagnetic immunity
The BM 75 is intended for use in the electromagnetic environment specified below. The customer or the user of the BM 75 should assure that it is

used in such an environment.
Immunity test

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 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 typical com-

mercial or hospital environment.

Mains power quality should be that of a typical com-

mercial or hospital environment. If the user of the BM 75

requires continued operation during power mains inter-

ruptions, it is recommended that the BM 75 be powered

from an uninterruptible power supply or a battery.

Power frequency (50/60 Hz)

3 A/m

Power frequency magnetic fields should be at levels

characteristic of a typical location in a typical commer-

cial or hospital environment.

NOTE: U
