Figure 2.2-1 shows the location and connection configuration for the single AC line input
(180-264 VAC). The AC wiring should be terminated with NO. 8 ring terminals and secured
to the 8-32 male terminals on the T3000 with nut and lock-washer. A safety cover, with
strain relief, covers the AC input connections.
CAUTION
Figure 2.2-2 shows the location of the bus bars for the two output sections and defines the
polarity relative to each other. Note that the Output-2 positive bus bar is common with the
T3000 signal ground.
CAUTION
Figure 2.2-3 shows how the auxiliary C-shaped and flat bus bars are utilized to connect the
two output sections of the T3000 in the parallel configuration. Cables to the thermal
sources (usually the feedthrough terminals of the vacuum chamber) must be terminated in
a suitably current rated solderless connector with a ¼-inch bolt hole for connection to the
bus bars.
