immunity-for all EQUIPMENT and SYSTEMS (see 6.8.3.201 a) 6))
Guidance and manufacturer’s declaration-electromagnetic immunity (T.202)
The EHY-2000plus is intended for use in the electromagnetic environment specified below. The
customer or the user of the EHY-2000plus should assure that it is used in such environment.
Electromagnetic environment -
guidance
Electrostatic
discharge (ESD)
IEC 61000-4-2
Floors should be wood, concrete or
ceramic tile. If floors are covered
with synthetic material, the relative
humidity should be at least 30%.
Electrical fast
transient/burst
IEC 61000-4-4
±2kV for power
supply lines
±1kV for input/
output lines
±2kV for power
supply lines
±1kV for input/
output lines
Mains power quality should be that
of a typical commercial or hospital
environment.
±1kV differential

±2kV common
mode
±1kV differential

Mains power quality should be that
of a typical commercial or hospital
environment.

<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

Mains power quality should be that
of a typical commercial or hospital
environment. If the user of EHY-
2000plus requires continued
operation during power mains
interruptions, it is recommended that
the EHY-2000plus be powered from
an uninterruptible power supply or a
battery.
Power frequency
(50/60Hz) magnetic
field
IEC 61000-4-8
Power frequency magnetic fields
should be at levels characteristic of
a typical location in a typical
commercial or hospital environment.
NOTE UT is the a.c. mains voltage prior to application of the test level.
