Guidance and manufacturer’s declaration-electromagnetic immunity

The ET1928L is intended for use in the electromagnetic environment specified below. The customer or the user

of the ET1928L 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% U

T <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 ET1928L

on power supply requires continued operation during power

input lines 40% U

T 40% UT mains interruptions, it is recommended that

(60% dip in UT) (60 % dip in UT) the ET1928L be powered from an

IEC 61000-4-11 for 5 cycles for 5 cycles uninterruptible power supply or a battery.

70% U

T 70% UT

(30% dip in UT) (30% dip in UT)

for 25 cycles for 25 cycles

<5% U

T <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 U

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