2 Reversing Contactor Kit for Non-Regenerative FlexPak Plus DC Drives
Installing the Reversing Contactor
Refer to figure 1 and to instruction manual D-3900 to identify drive terminals and connectors. To install the
Reversing Contactor in your non-regenerative FlexPak Plus DC drive:
Step 1. Disconnect, lock out, and tag input power to the drive.
Step 2. Remove the drive cover and verify that no voltage is present at the drive’s AC input terminals,
L1 and L2.
Step 3. Remove the auxiliary mounting bracket from the drive by removing the four mounting screws on each
side. Lift the bracket up and out of the way so you can access the mounting area.
Step 4. Mount the Reversing Contactor’s mounting bracket on the back of the auxiliary panel to the right of the
M-contactor and below the Dynamic Braking kit (if installed). The mounting bracket should have two
legs down and one leg up when mounted correctly. The panel is pre-drilled for the three 8-32 x 3/8
screws provided with the Reversing Contactor kit.
Step 5. Remove the two 8-32 x 3/4 screws from the Reversing Contactor’s mounting bracket.
Step 6. Make sure gray jumper wire 67 is connected to Reversing Contactor terminal 2.
Step 7. Make sure orange jumper wire 139 is connected to Reversing Contactor terminal 1.
Step 8. Place the L-shaped insulator sheet (labeled 410296-37A) between the Reversing Contactor and the
insulating mounting plate. Position the sheet to insulate the contactor from the auxiliary panel.
Step 9. Mount the reversing contactor, insulator sheet, and insulating mounting plate on top of the mounting
bracket with the insulating mounting plate on the bottom. Fasten the assembly using the two
8-32 x 3/4 screws removed in step 5.
Step 10. Remove J9 from the Regulator board (located below the REV connector near the top of the board).
Step 11. Connect the Reversing Contactor’s four power terminals to the four power terminals on the drive’s
M-contactor, as shown in figure . The armature connections, A1 and A2, between the contactors are
reversed (terminals 3 to 4 and 4 to 3).
Step 12. Drives with Dynamic Braking Kits Installed: Connect the Dynamic Braking kit between the two
corresponding normally-closed (NC) contacts on the M-Contactor and the Reversing Contactor. Refer
to instruction manual D2-3378 for information on installing the Dynamic Braking kit.

ATTENTION: Do not install modification kits with power applied to the drive. Disconnect, lock
out, and tag all sources of incoming AC power to the drive before attempting such installation.
Verify that no voltage is present at the drive’s AC input terminals, L1 and L2. Failure to observe
this precaution could result in severe bodily injury or loss of life.
ATTENTION: The user is responsible for conforming with all applicable local, national, and
international codes. Failure to observe this precaution could result in damage to, or destruction
of, the equipment.
