EMC information
Guidance and manufacturer’s declaration - electromagnetic emissions
Power-LOAD is intended for use in the electromagnetic environment specified below. The customer or the user of
Power-LOAD should assure that it is used in such an environment.

Electromagnetic environment
RF Emissions
CISPR 11
Group 1
The Power-LOAD system 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
Group 2
The Power-LOAD system must emit
electromagnetic energy in order to perform
its intended function. Nearby electronic
equipment may be affected.
RF Emissions
CISPR 11
Class A
The Power-LOAD system is suitable for use
in all establishments other than domestic
and those directly connected to the public
low-voltage power supply network that
supplies buildings used for domestic
purposes.
Recommended separations distances between portable and mobile RF communications equipment and Power-
LOAD
Power-LOAD is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of Power-LOAD can help prevent electromagnetic interferences by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and Power-LOAD 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. Note 1: At 80
MHz and 800 MHz, the separation distance for 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.
