3.6 Output Connections
3.6.1 Output Wiring
The output terminal blocks, TB1A and TB1B are located at the front of the unit
behind the bottom access panel. See Figure 3-2 for details.
Three phase output line connections are made to terminal block TB1A. The
phase outputs are labeled A, B and C. The neutral connection (if needed) can
be made on terminal block TB1B. If the model used is an MX30-1, MX30-3Pi,
MX45-1 or MX45-3Pi with single-phase capability, the single-phase A output
connection is available on TB1B as well. Note that the neutral for either single
or three-phase mode is always located on TB1B. The neutral connection is
always required for single-phase output mode on an MX30-3Pi or MX45-3Pi and
may be used if needed for the EUT for all three-phase output modes.
The external sense inputs allow the power system output voltages to be
monitored directly at the load and must be connected at TB2 when the sense is
programmed for external. The external sense input does not have to be
connected when Internal Sense is programmed. The external sense wires are to
be connected to TB2 on the rear panel and should be run using a twisted
shielded cable. See Figure 3-4 for location of TB2 and Figure 3-5 for shield
connection detail.
NOTE: For External Sense connection, a shielded cable MUST be used
with the shield connected to chassis ground at the Ext. Sense
connector. (See Figure 3-5).
External sense is recommended for multi-cabinet systems is the output wiring
from the cabinets to the common output terminal block supplied is not of equal
length.
