3.2 Grounding Of Bus Cable Shield In Opt-C4
The bus cable shield can be grounded to the frame of the frequency converter through an RC
filter located on the OPT-C4 option board.
Note: Normally, the C4 option board has already been installed in slot E of the control C4
Option board. It is not necessary to detach the whole C4 Option board for the grounding of
the bus cable shield. Just detach the terminal block.
