Installation & Initial Turn-On
2.5.5.3 Dual Power Supply Option
To add redundancy the Z2 can be configured with an optional second power supply.
The installation procedure only changes slightly for this configuration. The
following lists only the additions to the above procedure.
a.
Before rolling the power supply all of the way into the cabinet, connect the
blue ribbon cable labelled W12 to J4 on the power supply on the left side of
the tray (PS2). The supply may now be rolled all of the way into the cabinet.
b.
The wago block connection on the front of the power supply tray, 1A17TB1,
has 6 connections whereas the single supply version has only 4. The connec-
tions are shown in Figure 2-6 and are as follows:
1. Wire #1 connects to terminal #1
2. Wire #2 connects to terminal #3
3. Wire #40 connects to terminal #5
4. Wire #41 connects to terminal #6
NOTE:
Terminals 1 and 2 are connected inside the Wago block as are terminals 3 and 4.
c. The +52Vdc output and ground from the second supply must also be con-
nected. Wire #81 connects to feedthru C4. Ground wire #152 connects to the
ground stud at the top front of the power supply compartment (above C3 and
C4). See Figure 2-5.
