Due to the built-in LCL filter the unit will not feed the main wire with high dU/dt signals. That reduces the radiated
emission through the power cable. Cable screen/shielding can thus be omitted allowing the mains cables to be connected
without considering EMC requirements.
The Active Filter will be able to run at long cable runs. Cable length is limited by the voltage drop. It is advised to keep the
cable lengths to less then 200m.
For protection of the active filter, the recommended fuses must be used or the unit must be with built-in fuses.
Recommended fuses can be seen in the tables of the fuse section. Always ensure that proper fusing is made according to
local regulation.
