A2.2 Electromagnetic Immunity
Guidance and manufacture’s declaration – electromagnetic immunity
The SD5/SD6 is intended for use in the electromagnetic environment specified below. The customer or
the user of SD5/SD6 should assure that it is used in such an environment.
Immunity test IEC 60601 test level

Floors should be wood,
concrete or ceramic tile. If
floor are covered with
synthetic material, the relative
humidity should be at least
30%.

IEC 61000-4-11
<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
<5% UT (>95% dip in
UT) for 5s
<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
<5% UT (>95% dip in
UT) for 5s
Mains power quality should be
that of a typical commercial or
hospital environment. If the
user of the SD5/SD6 requires
continued operation during
power mains interruptions, it is
recommended that the
SD5/SD6 be powered from an
uninterruptible power supply
or a battery.
NOTE UT is the a.c. mains voltage prior to application of the test level.
