Product Description
Installation of the Reversing Contactor enables a single-phase, non-regenerative FlexPak™ Plus DC drive to provide both forward and reverse motor control. The standard factory-shipped drive offers unidirectional motor control only.
When the Reversing Contactor kit is installed, the drive’s M-contactor functions as the forward contactor. Motor direction is manually selected using the forward/reverse switch on the operator’s control station (M/N 9C300). See FlexPak Plus drive instruction manual D-3900 for information on the control station.
Read and understand this manual and other applicable manuals in their entirety before proceeding. Failure to observe this precaution could result in severe bodily injury or loss of life.
The Reversing Contactor is pre-assembled at the factory and includes all of the necessary jumper wires and mounting hardware. The contents of the kit are listed in table 1.

Installing the Reversing Contactor
ATTENTION:
out, and tag all sources of incoming AC power to the drive before attempting such installation.

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,
Step 3. Remove the auxiliary mounting bracket from the drive by removing the four mounting screws on each
Step 5. Remove the two 8-32 x 3/4 screws from the Reversing Contactor’s mounting bracket.
V erify that no voltage is present at the drive’s AC input terminals, L1 and L2. Failure to observe this precaution could resu lt in severe bodily injury or loss of life.
ATTENTION:

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.
