ELECTROMAGNETIC IMMUNITY GUIDANCE
ELECTROMAGNETIC IMMUNITY GUIDANCE
Guidance and manufacturer’s declaration – electromagnetic immunity
The LaserBand 41 is intended for use in the electromagnetic environment specified below. The customer or the user of LaserBand 41 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 relative humidity
should be at least 30%.
Electrical fast transient/burst
IEC 61000-4-4 ± 2kV for power supply lines
± 1kV for input/output lines ± 2kV for power supply lines
Not Applicable Mains power quality should be that of a typical commercial
or hospital environment.
Surge IEC 61000-4-5 ± 1kV line(s) to line(s)
± 2kV line(s) to earth ± 1kV differential mode
Not Applicable Mains power quality should be that of a typical commercial
or hospital environment.
Voltage dips, short
interruptions and voltage
variations on power supply
input lines
IEC 61000-4-11 <5% UT (>95% dip in UT) for 0.5 cycle
40% UT (60% dip in UT) for 5 cycles
70% UT (30% dip in UT) for 25 cycles
<5% UT (>95% dip in UT)for 5 sec <5% UT (>95% dip in UT) for 0.5 cycle
40% UT (60% dip in UT) for 5 cycles
70% UT (30% dip in UT) for 25 cycles
<5% UT (>95% dip in UT) for 5 sec Mains power quality should be that of a typical commercial
or hospital environment. If the user of the LaserBand
41 requires continued operation during power mains
interruptions, it is recommended that the LaserBand 41 be
powered from an uninterruptible power supply or a battery.
Power frequency (50Hz/60Hz)
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 UT is the a.c. mains voltage prior to application of the test level.
