pending on the application
A
Component HCS01 (more powerful than component B); con‐
nected to other components via DC bus
B
Component HCS01 (less powerful than component A); connec‐
ted to other components via DC bus
Bb

Central Supply
Option 1:
Several powerful HCS01 components (of the same size!) are connected
to the mains and supply other components via the common DC bus con‐
nection. This requires balancing chokes between supply mains and
components.
Components marked with gray background color: Option‐
al, depending on the application; the choke is used to re‐
duce current harmonics
A
Component HCS01 (more powerful than component B; all
components A identical); connected to supply mains via
balancing chokes; connected to other components via DC
bus
B
Component HCS01 (less powerful than component A);
connected to other components via DC bus
Bb
Bb relay contact wiring
M
Module bus
Fig. 4-24:
Group Supply; Several HCS01 Components Connected to
Supply Mains
Option 2:
All HCS01 components (of the same size!) are connected to the mains
and interconnected via the common DC bus connection. This requires
balancing chokes between supply mains and components.
