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.

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

commercial or hospital environment.

Voltage dips, short interrup-

tions and voltage variations on

power supply input lines

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

is the a.c. mains voltage prior to application of the test level.
