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
mode
±2 kV common
mode Complies 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 <100% drop, 0/5
periods, 0°, 45°,
90°, 135°, 180°, 225°,
270°, 315°
100% dip, 1 period
30% dip, 25/30
periods
40% dip for 5 cycles Complies Mains power quality should be that of a typical
commercial or hospital environment. If the user of
the
EMU40EX requires continued operation during
power mains interruption, it is recommended that
the
EMU40EX be powered from an uninterruptible
power supply or a battery.
Power frequency
(50/60 Hz) magnetic
field
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.
