AT235 Instructions for Use - EN Page 55
Guidance and Manufacturer’s Declaration - Electromagnetic Immunity
The AT235 is intended for use in the electromagnetic environment specified below. The customer or the user of the AT235 should
assure that it is used in such an environment.
Immunity Test IEC 60601 Test
Compliance Electromagnetic
Electrostatic Discharge
(ESD)
IEC 61000-4-2
+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 greater than 30%.
Electrical fast
transient/burst
IEC61000-4-4
+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 residential
environment.
Surge
IEC 61000-4-5
+1 kV differential mode
+2 kV common mode
+2 kV common mode
Mains power quality should be that of a
typical commercial or residential
environment.
Voltage dips, short
interruptions and voltage
variations on power
supply 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
for 0.5 cycle
40% UT (60% dip in UT) for
5 cycles
70% UT (30% dip in UT) for
25 cycles
<5% UT
Mains power quality should be that of a
typical commercial or residential
environment. If the user of the AT235
requires continued operation during
power mains interruptions, it is
recommended that the AT235 be
powered from an uninterruptable
power supply or its battery.
Power frequency (50/60
Hz)
3 A/m 3 A/m Power frequency magnetic fields
should be at levels characteristic of a
typical location in a typical commercial
or residential environment.
Note: UT is the A.C. mains voltage prior to application of the test level.
