3.2.2.2. Electrical specifications of the Lorain CIP shelf
Each rectifier position provides interconnection points for the AC input, DC
output, and the control and alarm data bus (CAN protocol) for the rectifier.
The AC supply can be brought into the shelf through receptacles located at
the rear of the shelf (rear access), or on the left side of the shelf as viewed
from the front (front access).
The control and distribution section provides interconnection points for the
System Manager CIP and connecting points for the –48 V and BR+ cables
and wires for the batteries and the loads. The DC cables and wires for the
battery return reference (BRR), the batteries and the load are brought into the
shelf through the right side of the shelf as shown in Figure 3.14 and Figure
The total DC discharge capacity of the distribution section for an AP6C55CA
Lorain CIP
power system is 120 amperes. Note that because of the reduced
rectifier capacity, this capacity is limited to 90 amperes in an AP6C55CB
Lorain CIP 4890 power system. It may also be limited to lower values when
used in a N+1 application.
Refer to sections 3.2.3, 3.2.4 and 3.2.5 for the electrical specifications
applying specifically to the controllers, rectifiers and distribution section
respectively.
