MX Series 72
3.6.8 Multi-Chassis Output Connections
If two or more MX 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 MX 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 MX
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 supplied terminal blocks are shown in Figure 3-14.
Note that even if the EUT is a three-phase delta input, the output neutrals of the
MX chassis' must be connected for the system to work correctly.
