EMC Directive

This inverter device is a component intended for implementation in machines or systems for the capital
goods industry. They have been tested to meet Council Directive 89/336 Electromagnetic Compatibility
(EMC) and all applicable standards (listed in the technical construction file).
With the specified EMC-filters and the measures as described in this guidelines the GV3000/SE can be
operated CE-conform according to product standard EN 61800-3 as follows:
Emission limits for class A, group 1, in the
first environment, (public LV supply network)
Emission limits for class A, group 2
class A, group 2* in the
nd
2 environment (industrial supply network)
Immunity: Performance criteria A in the
nd
2 environment (industrial supply network)
** To meet the high frequency emission limits for the first environment, class A, group 1 (public LV
supply network) inverters type AC003 - 030, 039/044 must be built into a EMC-tested control cubicle.
The motor cable length has no Influence on EMC-standards, however cable length influences the
capacitive earth currents. (see chapter 3, Motor Connection).
CAUTION: The conformity of the drive and filter to any standard does not guarantee that the entire
installation will conform. Many other factors can influence the total installation and only
direct measurements can verify total conformity. It is therefore the responsibility of the
machine manufacturer, to ensure, that the EC-conformity is met.

Disturbances

Conducted, High Frequency Disturbances (0,15 - 30 MHz)
Depending on location - first environment (residential or public low voltage supply network), second
environment (industrial supply network) - and inverter rating, different limits are permitted, whereas the
practical limit for the first environment is 100 A. For inverters with AC line input current below 100 A,
which are located in the first, as well as in the second environment, lower limits are required than for
inverters above 100 A in the second environment.

Radiated, High Frequency Disturbances (30 - 1000 MHz)

The radiated disturbances of the inverter will be kept below den limits, if for the installation the same
EMV-Measures are taken into account as for the conducted disturbances.

Conducted, Low Frequency Disturbances (Harmonics 0,1 - 2,5 kHz)

Inverters with non sinusoidal AC line input current always generate current harmonics. The degree of
disturbances, caused by harmonics, depends not only on the supply network (total Impedance), but also
on the relative inverter power.
Voltage harmonics may cause disturbances e.g. in centralized telecontrol systems or other electrical
consumers. If high power inverters are connected to low voltage distribution networks with low fault
levels, the resulting voltage harmonic content could be claimed by the power supply authority to exceed
the permitted values, stated in their regulations.
If the limits of the individual harmonic voltage portions are exceeded, the harmonic currents must be
reduced in the supply network e.g. by means of additional line chokes or harmonic filters.
On request Rockwell Automation will provide the harmonics current spectrum generated by each
GV3000 or perform a harmonics analysis for the complete installation based on delivered data.
Immunity
Immunity against Conducted and Radiated, High Frequency Disturbances
The GV3000 frequency inverters have been tested to fulfill the Immunity requirement in the first, as well
as in the second environment.
