B.
If the regulator has a source-side PT input present
and it will be used to supply a source-side voltage
for reverse power operation, take the following
steps:
i.
Connect the Siemens U2 lead to the top of
the V6 switch.
ii.
Using the supplied tool, remove the white/
brown number 23 lead from the bottom
section of V1 and place it at the bottom of V6.
iii.
FC 146 on the control must be set to Vin
Mode.
iv.
FC 44
(enter function code 44 and then
press the down arrow) must be set to the
source-side PT ratio of the Siemens voltage
regulator.
21. Connect remaining leads per Table 1 and Figures 6 and
7. A decal (see Figure 1) is located in the bottom of the
control box as a reference for wiring connections from
the Siemens voltage regulator to the CRA terminal
board and switches. The Siemens connections are
labeled in Red and Eaton's identification is labeled in
Black.
22. If the motor capacitor had been located in the old
control box, install and reconnect it in the CRA control
box and secure the capacitor.
23. Verify that:
A.
The V1 and V6 knife blade switches are open.
B.
The C knife blade is closed (shorted).
24. If not already installed, install the control panel on the
hinges and plug in the connector.
25. Proceed to
Control Setup
