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
motors are category C2, corresponding to CISPR11,
20
group 1, class A, and may be installed in residential
25
areas (first environment).

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.
