• In accordance with EN 61800-3 – Adjustable speed electrical power drive systems. Part 3. EMC
requirements and specific test methods. See table 8.1
• The OJ-DV product line fulfils the “residential level” for emissions as per EN-61000-6-3 and the
“industrial level” for immunity as per EN-61000-6-2 with up to 5 metre shielded motor cables.
(15kW is limited to up to 4 metre motor cables).
• Longer motor cables can be used. Industrial level for both immunity and emissions can be fulfilled,
depending on the cable capacity as well as the motor capacity.
• By reducing the motor cable length, it is possible to install up to 6 OJ-DVs in the same unit with
EN-61800-3 C1 & C2 still being fulfilled.
7.6. Harmonic distortion
The OJ DV 1-phase variants complies with IEC 61000-3-2 class A. The OJ DV 3-phase variants
comply with IEC 61000-3-12 provided that the short-circuit power S
sc
is greater than or equal
to that specified 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 consulting with distribution
network operator if necessary, that the equipment is connected only to a supply with a short-circuit
power S
sc
greater or equal to as specified. The OJ DV 3-phase variants complies with IEC 61000-3-
12 Table 5 for asynchronous motors and PM motors with sinusoidal back-EMF.”
Supply short circuit power:
Ensure that the short circuit power of the supply Ssc is greater than or equal to:
