IMMUNITY tests IEC 60601- TEST LEVEL COMPLIANCE LEVEL GUIDANCE ON ELECTRO-
MAGNETIC ENVIRONMENT
Electrostatic discharge (ESD)
(IEC 61000-4-2) ± 6 kV contact discharge
± 8 kV discharge through
air ± 6 kV contact
discharge
± 8 kV discharge
through air Flooring should be wood,
concrete or ceramic tiles. If the
floor covering is of synthetic
material, relative air humidity
must be at least 30%.
Rapid transient electrical
interfer-ence/bursts
(IEC 61000-4-4) ± 2 kV for mains cables
± 1 kV for input and
output cables ± 2 kV for mains cables
± 1 kV for input and
output cables The quality of the mains
voltage should be similar to
that of a typical business or
hospital environment.
Surge voltages
(IEC 61000-4-5) ± 1 kV outer cable -
outer cable
± 2 kV outer cable -
earth ± 1 kV outer cable -
outer cable
± 2 kV outer cable -
earth The quality of the mains
voltage should be similar to
that of a typical business or
hospital environment.
Voltage dips, short-term
interruptions and variations
in mains voltage
(IEC 61000-4-11) < 5% UT
(>95% dip in UT)
for ½ period
40% UT
(60% dip in UT)
for 5 periods
70% UT
(30% dip in UT)
for 25 periods
< 5% UT
(>95% dip in UT)
for 5 sec
< 5% UT
(>95% dip in UT)
for ½ period
40% UT
(60% dip in UT)
for 5 periods
70% UT
(30% dip in UT)
for 25 periods
< 5% UT
(>95% dip in UT)
for 5 sec
The quality of the mains
voltage should be similar to
that of a typical business or
hospital environment.
If the ProLift Cacero series hoist
is to operate also when the
power supply is interrupted,
it is recommended to supply
the ProLift Cacero hoist via an
uninter-ruptible power supply
or a battery.
Magnetic field at the supply
frequency (50/60 Hz)
(IEC 61000-4-8) 3 A/m 3 A/m Magnetic fields at mains
frequency should be similar
to those found in a typical
business or hospital environ-
ment.
REMARKS: UT is the mains AC voltage before the test level is applied
