Remarks
Cable lengths should always be as short as possible.
The table is based on correct EMC wiring with shielded cable and proper
EMC installation.
Voltage drop over the complete system must be less than 10% of the
main supply.
* Conducted interference limits on unshielded motor - lines according to
EN61800-3, table 16.
** No marks in a row, means that there is no need to take precautions
