Electromagnetic Environment Guidelines
Discharge of static electricity
(ESD) acc. to IEC 61000-4-2
± 6 kV contact
discharge
± 8 kV
air discharge
± 6 kV
± 8 kV
Floor surfaces should be of wood or concrete
or be covered with ceramic tiles. If the floor
is covered with synthetic material, the
relative humidity must be at least 30%.
Transient electrical
disturbances in rapid
succession / bursts acc. to
IEC 61000-4-4
± 2 kV
for mains cables
± 1 kV
for input and
output lines
± 2 kV
------------------
± 1 kV
The quality of the power supply voltage
should be equal to that of a typical business
or hospital environment.
Voltage bursts (Surges)
acc. to IEC 6100-4-5
± 1 kV
normal-mode
voltage
± 2 kV
common-mode
voltage
± 1 kV
± 2 kV
The quality of the power supply voltage
should be equal to that of a typical business
or hospital environment.
Voltage dips, brief power
outages and fluctuations in
power supply voltage acc. to
IEC 61000-4-11
< 5% U

for 25 periods
<5% U
τ
(> 95% dip in U
τ
) for 5 s
The quality of the power supply voltage
should be equal to that of a typical business
or hospital environment.
If the user of Oculus equipment requires
continuous operation even in the event of
power outages, it is recommended that the
equipment be powered by an outage-proof
power supply or a battery.
Magnetic field for power
supply frequency (50/60 Hz)
acc. to IEC 61000-4-8
3 A/m
3A/m
Magnetic field levels for power supply
frequencies should be equal to those typically
found in business and hospital environments.
Note: U
τ
is the a.c. supply voltage prior to application of the test level
