Internal signal line connection
Feed-in modules are used to connect the feed-in conductors.
They connect the power supply to the main strands of the
maxGUARD station. The AMG ELM electronic load moni-
tors can be controlled and monitored using active feed-in
modules. Active feed-in modules drive the internal bus and
connect the internal signal line to an external control unit. An
active feed-in module and the connected load monitors form
unit concerning the control.
