CE-Conformity

EMC Directive

This converter 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 WebPak 3000 can

be operated CE-conform according to product standard EN 61800-3.

ATTENTION: 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 converter rating different limits are permitted, whereas the

practical limit for the first environment is 100 A. For converters 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

converters above 100 A in the second environment.

Radiated, High Frequency Disturbances (30 - 1000 MHz)

The radiated disturbances of the converter will be kept below the 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)

Converters 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 converter power.

Voltage harmonics may cause disturbances e.g. in centralized telecontrol systems or other electrical
consumers. If high power converters 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 active or passive harmonic filters.

On request Rockwell Automation will provide the harmonics current spectrum generated by each
WebPak 3000 or perform a harmonics analysis for the complete installation based on delivered data.

Immunity

Immunity against Conducted and Radiated, High Frequency Disturbances

The WebPak DC-converters have been tested to fulfill the Immunity requirement in the first, as well as in
the second environment.
