Looping through the DC bus con‐
nection via DC bus connector X77
Fig. 4-34: Looping through via DC bus connector
The DC buses of the individual devices are connected via the DC bus con‐
nectors X77.
When the devices are supplied via group supply, the DC bus connector X77
of the last infeeding device is the limiting factor in the DC bus group.
Device arrangement: The higher the power consumption of a de‐
vice, the nearer to the supplying devices it has to be arranged.
Example:
1, 2 HCS01.1E-W0028 (supplying devices)
3, 4, 5 HCS01.1E-W0018 (supplied devices)
Fig. 4-35: Looping through
On the left, the two supplying HCS01.1E-W0028 devices have been ar‐
ranged; to their right the three supplied HCS01.1E-W0018 devices.
The DC bus connector of the second device from the left (2) limits the possi‐
ble number of devices at the common DC bus.
