The “VM 9100RM III therapy system” is intended for operation in the electromagnetic
environment indicated below.
The operator has to ensure that the “Therapy System VM 9100RM III” is operated in this
kind of environment.
Electromagnetic
environment - Guidelines
Electrostatic discharge
(ESD) acc. to IEC 61000-
4-2
±8kV contact
discharge
±15kV air
discharge
±8kV contact discharge
±15kV air discharge
Floors should be made of wood
or concrete or covered with
ceramic tiles. If the floor is
covered with synthetic
material, the relative humidity
has to be at least 30%.
Electrical fast
transient/burst acc. to IEC
61000-4-4
±2kV for power
cables
±1kV for input
and output cables
±2kV for power cables
±1kV for input and output
cables
The quality of the supply
voltage should correspond to a
typical business or hospital
environment.
Surges acc. to
IEC 61000-4-5
±1kV normal
mode voltage
±2kV common
mode voltage
±1kV normal mode
voltage
±2kV common mode
voltage
The quality of the supply
voltage should correspond to a
typical business or hospital
environment.
Voltage dips, short
interruptions and voltage
variations acc. to IEC
61000-4-11
<5% U
T
(>95%
dip of U
T
) for ½
period
40% U
T
(60% dip
of U
T
) for 5
periods
70% U
T
(30% dip
of U
T
) for 25
periods
<5% U
T
(>95%
dip of U
T
) for 5 s
<5% U
T
(>95% dip of
U
T
) for ½ period
40% U
T
(60% dip of U
T
)
for 5 periods
70% U
T
(30% dip of U
T
)
for 25 periods
<5% U
T
(>95% dip of U
T
)
for 5 s
If the user requires the
continued functioning of the
VM 9100RM III therapy
system even if the energy
supply is interrupted, it is
recommended to supply the
VM 9100RM III therapy
system with power using an
uninterrupted power supply or
a battery.
Power frequency
magnetic field (50-60Hz)
acc. to IEC 61000-4-8
Magnetic fields at mains
frequency should correspond to
the typical values as found in
business and hospital
environments.
Comment: UT = Alternating mains voltage prior to the application of the test levels.
