Removing 10-Position Terminal Strip
1. If the regulator and or control is energized perform the
following steps before installing the upgrade.
2. Open the V1 and V6 (if present) knife-blade switches
on the back panel. Close the C knife-blade switch
to short the CT. See Figure 1. In some of the earlier
regulators, the C shorting switch must to be pulled
open in order to short the CT.
3. Locate the orange HS lead. Remove the HS lead
terminal from the lower row of screws on TB1.
4. Performing the steps above will isolate the TB2
circuits.

bar. See Figure 4.
3. Use a standard screwdriver and remove the control
fanning strip from the bottom row of screws on TB2.
See Figure 4. Remove the control panel from the
control box hinges.
4. Remove the control wiring harness terminals from the
top of TB2. See Figures 3 and 4.
5. Use a standard screwdriver to remove the TB2 terminal
board mounting screws, there could be as many as
four screws. See Figure 4.

1. Once the 10-position terminal board is removed
from the back panel, remove the adhesive protector
from the back side of the 18-position terminal strip
assembly. See Figure 5.
2. Locate, center and place the 18-position terminal strip
assembly on to the back panel with the white wire
and metal jumper at the top. See Figure 6. The new
terminal strip assembly should be placed in the same
location as the old 10-position terminal strip. The DHR
label should be located on the right hand side of the
back panel with the terminal strip assembly installed.
3. Using a 1/4 inch nut-driver remove the nut and
lockwasher on the label bar on the DHR end of the
terminal board. Loosen the nut on the opposite end of
the label bar. Remove the label bar from the terminal
board stud on the DHR end. See Figure 7.
4. Wire the back panel wiring harness to the new TB2
terminal strip. The table below shows the wiring color
code and label location for each lead.

8. Place the control fanning strip on the bottom row of
screws. The white/orange wire on the fanning strip
should be located on the DHR terminal. See Figure 8.
9. Tighten all 18 screws on the fanning strip.
10. Connect the green ground lead on the control panel
to the back panel. From the items supplied, select the
appropriate hardware to be used for connecting the
ground lead. See Figure 9.
Figure 6.
11. Reconnect the orange HS lead back on to the terminal
labeled HS on TB1. See Figure 5.
Terminal Board Stud
12. To energize the front panel, the V knife-blade switches
must be closed and the C knife-blade switch placed in
the open operating position.
Information Notes
1. The white jumper lead must be connected from J to
G on TB2.
2. A metal jumper must be connected between terminals
BR and G. This jumper must be in place for automatic
operation. Another method to inhibit automatic
operation is by setting FC 69 to Blocked.

3. In a CL-1 series control the VM, motor supply,
supplied by RCT2, means that your VM lead on TB2
will be coming from the terminal board at RCT2.

4. If you are replacing a CL-1 series control and the
regulator is set up for reverse power flow and you
want to use the present setup, which would include
an internal differential PT and a third RCT. You must
connect a lead from the terminal board on RCT 3 to
TB2-V7 and remove the auxiliary reverse power flow
panel.
Control Fanning Strip
5. If you are replacing a CL-2 or CL-2A front panel and
the regulator is set up for reverse power flow, and you
want to use the present setup, that would include an
internal differential PT and a second ratio correction
transformer (RCT2). You must connect a lead from the
terminal board on RCT2 to TB2-V7 and remove the
auxiliary reverse power flow panel.
6. When replacing a CL-1, CL-2, CL-2A or CL-4 series
control panels with a CL-5C, CL-5C you do not need
to use the internal differential PT or RCTs for reverse
power flow. Refer to the CL-5C or CL-5 series control
manual, S225-10-10 for instruction on setting up for
reverse power flow operations.
