29. Other technical data
EMC (electromagnetic compatibility)
Standard used: EN 61800-3.
The table below shows the emission category of the
motor.
C1 fulfils the requirements for residential areas.
Note: When connected to a public network, 11 kW
motors do not comply with the partial weighted
harmonic distortion (PWHD) requirements of EN
61000-3-12. If required by the distribution network
operator, compliance can be obtained in the
following way:
The impedance of the mains cables between the
motor and the point of common coupling (PCC) must
be equivalent to the impedance of a 50 m cable with
a cross-section of 0.5 mm.
C3 fulfils the requirements for industrial areas.
Note: When the motors are installed in residential
areas, supplementary measures may be required as
the motors may cause radio interference.
*
C1, if equipped with an external Grundfos EMC
filter.
Immunity: The motor fulfils the requirements for
industrial areas.
Contact Grundfos for further information.
