C) Wiring
•
Shielded wiring (screened cable) is required for motor wiring, and total length has to be kept
to less than 50m. When using motor cables longer than 50m, L2000 motor filters should be
installed. Directions for installing filters can be found in the L2000 installation manual.
•
Seperate the mains circuit wiring from the wiring used for signals or process circuit. Please
refer to the L2000 installation manual.
D) Installation
•
For L2000 series inverters, the filters described hereafter have to be used and the installation
notes have to be observed.
If installed according to the following directions, the frequency inverters comply with the following
standards:
Emmissions:
EN 61800-3 (EN 55011 group 1, class B)
Immunity:
EN 61800-3, industrial environments
For the best possible damping of interference, special line filters have been developed which
guarantee you easy assembly and installation along with the necessary electrical reliability.
However, effective EMC is only ensured if the suitable filter is selected for the particular drive and
installed in accordance with these EMC recommendations. Please choose the appropriate filter
using the table below:

Note:
All filters are designed for 50Hz/60Hz +/-5%.
The amount of line-conducted interference also increases as motor cable length increases.
Adherence to the interference limits for line-conducted interference is guaranteed on following way:
•
If maximum motor cable length is 10 m at maximum elementary
frequency:
Class „B“.
•
If maximum motor cable length is 20 m at elementary frequency 5 kHz:
Class „B“.
•
If maximum motor cable length is 50 m at maximum elementary
frequency:
Class „A“.
