Guidance and manufacturer’s declaration-electromagnetic immunity

The ET2400LM is intended for use in the electromagnetic environment specified below. The customer or the user

of the ET2400LM should assure that it is used in such an environment.

Immunity test	IEC 60601		Compliance level	Electromagnetic environment-
test level				guidelines
Electrostatic	±	6 kV contact	± 6 kV contact	Floors should be wood, concrete or
discharge(ESD)	±	8 kV air	± 8 kV air	ceramic tile. If floors are covered with
IEC 61000-4-2				synthetic material, the relative humidity
				should be at least 30%.
Electrical Fast	± 2 kV for power		± 2 kV for power	Mains power quality should be that of a
transient/burst	supply lines		supply lines	typical commerical or hospital
				environment.
IEC 61000-4-4	± 1 kV for input/output		± 1 kV for input/output
	lines		lines
Surge	± 1 kV line(s) to line(s)		± 1 kV line(s) to line(s)	Mains power quality should be that of a
IEC 61000-4-5	± 2 kV line(s) to earth		± 2 kV line(s) to earth	typical commerical or hospital
				environment.
Voltage dips, short	<5% UT		<5% UT	Mains power quality be that of a
interruption and	(>95% dip in UT)		(>95% dip in UT)	typical commerical or hospital
voltage variations	for 0.5 cycle		for 0.5 cycle	environment. If the user of the ET2400LM
on power supply				requires continued operation during power
input lines	40% UT		40% UT	mains interruptions, it is recommended that
	(60% dip in UT)		(60 % dip in UT)	the ET2400LM be powered from an
IEC 61000-4-11	for 5 cycles		for 5 cycles	uninterruptible power supply or a battery.
	70% UT		70% UT
	(30% dip in UT)		(30% dip in UT)
	for 25 cycles		for 25 cycles
	<5% UT		<5% UT
	(>95% dip in UT)		(>95% dip in UT)
	for 25 cycles		for 25 cycles
Power frequency	3 A/m		3A/m	Power frequency magnetic fields
(50/60 Hz)				should be at levels characteristic of a
magnetic field				typical location in a typical commerical
				or hospital environment.
IEC 61000-4-8
NOTE UT is the a.c. mains voltage prior to application of the test level.
