11.3 Other technical data
11.3.1 Ecodesign Directive
This product is out of scope of Directive 2009/125/EC and
Commission Regulation (EU) 2019/1781 due to Article 2 (3a), as
the variable speed drive (VSD) is integrated into a product and its
energy performance cannot be tested independently from the
product.
11.3.2
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.
Model J:
When connected to a public network, 15-HP
motors do not comply with the partial weighted harmonics
(PWH) 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 power cables between the motor
and the point of common coupling (PCC) must be
equivalent to the impedance of a 164 ft (50 m) cable.
Model K: This equipment complies with IEC 61000-3-12
provided that the short-circuit power S
SC
is greater than or
equal to the respective value described in the table below
at the interface point between the user's supply and the
public system. It is the responsibility of the installer or user
of the equipment to ensure, by consultation with the
distribution network operator if necessary, that the
equipment is connected only to a supply with a short-
circuit power S
SC
greater than or equal to the respective
value described in the table below.
