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

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.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio
a
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 Bluephase PowerCure is used exceeds the applicable
RF compliance level above, Bluephase PowerCure should be observed to verify normal operation. If abnormal performance is ob-served, additional measures may
be necessary, such as reorienting or relocating Bluephase PowerCure.
Over the frequency range 150 kHz to 80 MHz, field strength should be less than 10 V/m.NOTE: U

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

Table: According to IEC60601-1-2
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (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.
