5.6 Parallel Lines
The parallel lines are used for balancing the active and reactive currents/loads between parallel
running C6200 FlexGen modules. The signal level of the parallel lines can also be adapted to suit
other types of Littelfuse Selco load sharers (e.g. the Littelfuse Selco T4800).

Please note that terminal 28 (COM) is internally connected to terminal 32 (Supply minus). In

can cause noise to be injected into the application. Ground
loops happen when multiple COM connections between modules (e.g. parallel operating
C6200 units) exist. Ground loops can be avoid by only using terminal 32 as the common
connection point for all COM connections.
