RF emissions
CISPR 11
Group 1
The Vacuum Pump uses RF energy only for its internal function. Therefore, its RF emissions are very low and
are not likely to cause any interference in nearby electronic equipment.
RF emissions
CISPR 11
Class B
The Vacuum Pump is suitable for use in all establishments, including domestic establishments and those
directly connected to the public low voltage power supply network that supplies buildings used for
domestic purposes.

power mains interruptions, it is recommended that the Vacuum Pump be powered
from an uninterruptible power supply or a battery.

Portable and mobile RF communications equipment should be used no closer
to any part of the Vacuum Pump, including cables, than the recommended
separation distance calculated from the equation applicable to the frequency of
the transmitter.

where P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer and d is the recommended separation
distance in metres (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic
site survey
a
should be less than the compliance level in each frequency range
b
Interference may occur in the vicinity of equipment marked with the following
symbol:
Note:
At 80 MHz and 800 MHz, the higher frequency range applies.
Note:
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects
and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and
FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Vacuum Pump is used
exceeds the applicable RF compliance level above, the Vacuum Pump should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the Vacuum Pump.
b
Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m.
