Guidance and manufacturer’s declaration-electromagnetic immunity (T.202)
The WEY-2000plus device is intended for use in the electromagnetic environment specified below.
The customer or the user of the WEY-2000plus should assure that it is used in such an 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

±1kV for input/
output lines
Mains power quality should be
that of a typical commercial or
hospital environment.
±1kV differential

Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of WEY-2000plus requires
continued operation during
power mains interruptions, it is
recommended that the WEY-
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.
