Electromagnetic Environment - Guidance
Electrostatic
Discharge (ESD)
IEC 61000-4-2
±8 kV contact
±15 kV air
Complies Floors should be wood, concrete or ceramic
tile. If floors are covered with synthetic
material, the relative humidity should be at
least 30%.
Electrostatic fast
transient/burst
IEC 61000-4-4
±2 kV, 100Khz for
power supply lines
±1 kV, 100Khz for
input/output lines
Complies Mains power quality should be that of a
typical commercial or hospital environment.
Surge
IEC 61000-4-5
±1 kV differential

lines
IEC 61000-4-11
<100% drop, 0/5
periods, 0°, 45°,

Complies Mains power quality should be that of a
typical commercial or hospital environment. If
the user of the EEG32U requires continued
operation during power mains interruption, it
is recommended that the EEG32U be
powered from an uninterruptible power
supply or a battery.

IEC 61000-4-8
30 A/m Complies Power frequency magnetic fields should be at
levels characteristic of a typical location in a
typical commercial or hospital environment.
NOTE: UT is the AC supply voltage prior to application of the test level.
