Guidance and manufacturer's declaration - electromagnetic immunity
The Bluephase N MC is intended for use in the electromagnetic environment specified below. The customer or the user of the Bluephase N MC should
assure that it is used in such an environment.

"Bluephase N MC"
The Bluephase N MC is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The customer or the
user of the Bluephase N MC can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Bluephase N MC as recommended below, according to the maximum output power of the
communication equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be determined 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 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
Compliance level Electromagnetic environment - guidance
Portable and mobile RF communications equipment should not be used closer to any
part of the Bluephase N MC, 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 meters
(m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site sur-
vey,
Interference may occur in the vicinity of equipment marked with the following symbol:
environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the Bluephase N MC
is used exceeds the applicable RF compliance level above, the Bluephase N MC should
be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the Bluephase N MC.
Over the frequency range 150 kHz to 80 MHz, field strength should be less than 10 V/m.
