Guidance and manufacturer’s declaration – electromagnetic immunity
The FT 90 is intended for use in the electromagnetic environment specified below.
The customer or the user of the FT 90 should assure that it is used in such an environment.
Immunity test
IEC 60601 test level Compliance level Electromagnetic environment –
guidance
Electrostatic discharge
(ESD)
IEC 61000-4-2
6 kV contact
8 kV air
6 kV contact
8 kV air
Floors should be wood, concrete or
ceramic tile. If floors are covered with
synthetic material, the relative humi-
dity should be at least 30 %.
Electrical fast transient/
burst
IEC 61000-4-4
2 kV for power supply lines
1 kV for input/output lines
Not applicable Mains power quality should be that
of a typical commercial or hospital
environment.
Surge
IEC 61000-4-5
1 kV line(s) to line(s)
2 kV line(s) to earth
Not applicable Mains power quality should be that
of a typical commercial or hospital
environment.
interruptions and voltage
variations on power sup-
ply input lines
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 5 sec
Not applicable Mains power quality should be that
of a typical commercial or hospi-
tal environment. If the user of the
FT 90 requires continued operation
during power mains interruptions, it is
recommended that the FT 90 be pow-
ered from an uninterruptible power
supply or a battery.
Power frequency
(50/60 Hz) magnetic field
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 commer-
cial or hospital environment.
NOTE UT is the a.c. mains voltage prior to application of the test level.
