Table 2: Guidelines and manufacturer‘s declaration – Electromagnetic immunity – For all ME de-
vices and ME systems
The sentida nursing home bed is intended for operation in an electromagnetic environment as specied
below.
IMMUNITY TESTS
IEC 60601
TEST LEVEL
COMPLIANCE LEVEL
ELECTROMAGNETIC ENVIRONMENT –
GUIDELINES
Electrostatic
discharge (ESD)
(IEC 61000-4-2)
± 8 kV contact dis-
charge
± 15 kV air dis-
charge
± 8 kV contact
discharge
± 15 kV air dis-
charge
Floors should be wood, concrete, or
ceramic tile. If the oor is covered with
synthetic material, the relative humidi-
ty must be at least 30%.
Fast transient elec-
trical disturbances
/ bursts
(IEC 61000-4-4)
± 2 kV for mains
lines
± 1 kV for input and
output lines
± 2 kV for mains
lines
± 1 kV for input
and output lines
The quality of the supply voltage
should be that of a typical business or
hospital environment.
Surges
(IEC 61000-4-5)
± 1 kV outer conduc-
tor-outer conductor
voltage
± 2 kV outer conduc-
tor-ground voltage
± 1 kV outer
conductor-outer
conductor voltage
± 2 kV outer
conductor-ground
voltage
The quality of the supply voltage
should be that of a typical business or
hospital environment.
Voltage dips, short-
term interruptions
and uctuations in
the supply voltage
(IEC 61000-4-11)
< 5 % UT
(>95% dip of UT) for
½ period
40% UT
(60% dip of UT)
for 5 periods
70% UT
(30% dip of UT)
for 25 periods
< 5% UT
(>95% dip of UT) for
5 sec.
< 5 % UT
(>95% dip of UT) for
½ period
40% UT
(60% dip of UT)
for 5 periods
70% UT
(30% dip of UT)
for 25 periods
< 5% UT
(>95% dip of UT) for
5 sec.
The quality of the supply voltage
should be that of a typical business or
hospital environment.
If the user of the sentida nursing home
bed requires continuous operation
even in case of power supply inter-
ruptions, it is recommended that the
sentida nursing home bed is powered
by an uninterruptible power supply or
battery.
Magnetic eld at
the supply fre-
quency (50/60 Hz)
(IEC 61000-4-8)
30 A/m 30 A/m
Magnetfelder bei der Netzfrequenz
sollten den typischen Werten,
wie sie in der Geschäfts- und
Krankenhausumge bung vorzunden
sind, entsprechen.
