Valleylab FT10 Energy Platform User’s Guide
Standards and IEC Classifications
NOTE 1
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2
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 Valleylab FT10 FT Series Energy Platform is used exceeds the applicable RF
compliance level above, the Valleylab FT10 FT Series Energy Platform should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the Valleylab FT10 FT Series Energy Platform.
b.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communication
equipment and the Valleylab FT10 FT Series Energy Platform
The VLFT10GEN is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the system can help prevent
electromagnetic interferences by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the system as recommended below, according to the
maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be estimated using 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.
a.
For frequencies listed in the following table, use a separation distance of 0.3 m.
