Multi-Chassis Output Connections
If two or more BPS chassis are used to form a single power system, the outputs of all chassis need to be
combined (paralleled by phase). This can be done directly at the EUT if convenient or using the provided
heavy-duty terminal blocks. Two blocks are provided with multi-chassis systems, one 2-position block
and one 3-position block. These blocks allow up to four wires to be combined into one larger wire gauge
size wire. The outputs of the 2 or 3 BPS chassis are connected on one side of these blocks (Phase A,B and
C into the 3 position terminal and the neutral into the 2 position terminal.). The EUT can be connected to
the other side. Note that the wire size to the EUT should be sized up to accommodate the double or triple
currents per phase.
The dimensions of the typical supplied terminal blocks are shown in Figure 4-9.
Note: Even if the EUT is a three-phase delta input, the output neutrals of the BPS chassis' must be
connected together for the system to work correctly.
