Radio Frequency Interference Filter
a) WebPak 3000 converters with AC line input currents below 100 A:
If the RFI filter is connected, the HF emission limits for class A, group 1 (EN 55011) according to the
product standard EN 61800-3 are met and the drive is CE conform. This applies for the
1
st environment (residential) as well as for the 2 nd environment (industrial supply network).
b) WebPak 3000 converters with AC line input currents above 100 A:
If the RFI filter is connected, the HF emission limits of class A, group 1 (EN 55011) in the 2 nd
environment (industrial supply network) are met, as required in the past for the Generic Standard
EN 50081-2. This is recommended if e.g. in industrial estates high power converters and offices with
sensitive consumers are connected to the same supply transformer.
The filter must be connected into the three AC line input phases L1 - L3 of the WebPak 3000 in front of
the AC line reactor, as shown in figure B.1.
RFI Filter Selection
The RFI-Filters can be selected from Table 5.7 according to the permitted filter current and the
maximum operating voltage.
The permitted filter current is dependent on the application specific maximum continuous DC-current I
ad
of the drive, the DC-current form factor (FF) and the ambient temperature T.
The ambient temperature T is the max. temperature around the filter (typical 50 ° C inside cabinets for a
standard max. cooling air temperature of 40 ° C). Typical DC-current form factor FF = 1.05
For cabinet mounting with T = 50 ° C and FF = 1.05:
Filter current = maximum continuous DC-current I
ad
For other ambient temperatures (T) and form factors (FF) the continuous current of the filter can be
calculated as follows:
