3. Examine the pigtail retained earlier. If the
motor capacitor was located in the old
control box, do not cut the terminals from the
capacitor wires.
4. Cut all other terminals (if present) from the end
of the cable conductors.
5. Strip the insulation back approximately 5/16 of
an inch on each lead to be connected in the
new control box.
B. Hard-wire control cable:
1. Examine the control cable. Allow approximately
12" of lead length to protrude past the end of
the cable insulation. If necessary, strip some
of the outer insulation.
2. Remove the cable grip nut and rubber cable
grommet from the cable entrance of the new
control box.
3. Place the cable grip nut over the existing
control cable. Select one of the two supplied
cable grommets that best fits the existing
cable; place the grommet onto the control
cable.
4. If the motor capacitor was located in the old
control box, do not cut the terminals from the
capacitor wires.
5. Cut all other terminals from the end of the
cable conductors.
6. Strip the insulation back approximately 5/16 of
an inch on each lead to be connected in the
new control box.
7. Insert the control cable into the control-box
cable grip connector, seat the rubber grommet
and tighten the cable grip nut.
13. V6 connections and source-side PT input:
A.
If there is no source-side PT input or if there is a
source-side PT input, but the source-side voltage is
to be calculated by the control, the control box has
been pre-configured for this type of operation; no
further action is required.
B.
If the regulator has a source-side PT input present
and it will be used to supply a source-side voltage
for reverse operation, take the following steps:
i.
Connect the white/black 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 44
(enter function code 44 and then
press the down arrow) must be set to the
Internal PT ratio value found on the nameplate
for the system voltage.
14. Connect the remaining leads per Figures 13 and 14.
A decal (see Figure 4) is located in the bottom of the
control box as a reference for wiring connections from
Eaton's voltage regulator to the CRA terminal board and
switches. Eaton's connections are labeled in black.
15. 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.
16. Verify that:
A.
The V1 and V6 knife blade switches are open.
B.
The C knife blade is closed (shorted).
17. If not already installed, install the control panel on the
hinges and plug in the connector.
18. Important Step!
When installing the a CL-7 regulator
on McGraw-Edison voltage regulator manufactured in
1988 and earlier, it will be necessary to flip a switch
on the side of the control (see Figure 12). The switch
must be in the down position for the older regulators;
the neutral light will stay on all the time if it is not.
19. Proceed to
Control Setup
section of this manual.
