Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
The RA660 is intended for use in the electromagnetic environment specified below.
The customer or the user of the RA660 is should assure that it is used in such an
environment.
Immunity Test
IEC 60601 Test

Floors should be wood,
concrete or ceramic tile. If
floors are covered with
synthetic material, the
relative humidity should
be greater than 30%.

25 cycles
<5 % UT
Mains power quality
should be that of a typical
commercial or residential
environment. In case of a
power failure the RA660
will automatically shut
down within 10 s. If the
user of the RA660
requires continued
operation during power
mains interruptions, it is
recommended that the
RA660 be powered from
an uninterruptable power
supply or its battery.
Power frequency
(50/60 Hz)
IEC 61000-4-8
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.
