EMC (electromagnetic compatibility to EN 61800-3)
Motor
Emission/immunity
[hp]
Emission:
The motors are category C3, corresponding to
CISPR11, group 2, class A, and may be installed in
industrial areas (second environment).
If equipped with an external Grundfos EMC filter, the
20
motors are category C2, corresponding to CISPR11,
25
group 1, class A, and may be installed in residential
areas (first environment).
30
When the motors are installed in
residential areas, supplementary
measures may be required as the motors
may cause radio interference.
Motor sizes 25, and 30 hp comply with EN 61000-3-12
provided that the short-circuit power at the interface
point between the user's electrical installation and the
public power supply network is greater than or equal to
the values stated below. It is the responsibility of the
installer or user to ensure, by consultation with the
power supply network operator, if necessary, that the
motor is connected to a power supply with a short-
circuit power greater than or equal to these values:

20 hp motors do not comply with EN
61000-3-12.
By installing an appropriate harmonic filter between the
motor and the power supply, the harmonic current
content will be reduced. In this way, the 20 hp motor
will comply with EN 61000-3-12.
Immunity:
The motors fulfill the requirements for both the first and
second environment.
Contact Grundfos for further information.
