Siemens sinamics dcp Operating Instructions Manual page 41

The block diagram above shows a (maximum) configuration for the SINAMICS DCP together
with possible interfaces to a higher level controller.
● Fuses: See Chapter Components (Page 43)
● Precharging (precharging interface: precharging resistors and fuses): See Chapter
Precharging of the DC links (Page 240)
● Main contactors: See Chapter Components (Page 43)
● The connections "from the previous DCP" and "to the next DCP" are only required if
multiple SINAMICS DCPs are switched in parallel: See Chapter Parallel connection of
multiple SINAMICS DCPs (Page 269)
To prevent coupling of external interference into the cabinet, the shields for the cables used
must be grounded extensively as close as possible to the point of entry into the cabinet.
Suitable shield buses or comb bars can be used here.
These busbars must be connected conductively and extensively to the cabinet housing.
