- Network operation is possible with 9342 or 9343. Since P
DCtotal
is higher
than P
DC100%934X
, the network requires a second supply. The selection of
the regenerative power supply module is now only dependent on the
regenerative power.
3. Determine the second input:
- Network with 9342: Second input at 9328
- Network with 9343: Second input at 9328 or 9325
