2 Reversing Contactor Kit for Non-Regenerative MinPak Plus DC Drives
Installing the Reversing Contactor
Important: If a Dynamic Braking kit will be installed, it is easier to mount the dynamic braking resistor in the
drive chassis before installing the Reversing Contactor kit. The dynamic braking resistor must be
connected between two corresponding normally-closed (NC) contacts on the M-contactor and the
Reversing Contactor. Refer to the Dynamic Braking kit instruction manual.
Refer to your MinPak Plus DC drive instruction manual to identify drive terminals and connectors. A schematic
of the is shown at the end of this manual in figure 2.
To install the Reversing Contactor in your non-regenerative MinPak Plus DC drive:
Step 1. Disconnect, lock out, and tag input power to the drive.
Step 2. Remove the drive cover.
Step 3. Verify that no voltage is present at the drive’s AC input terminals, L1/181 and L2/182.
Step 4. Remove the two screws that fasten the mounting bracket for the terminal blocks and power on/off
circuit breaker to the drive. Move this assembly out of the way.
Step 5. Position the Reversing Contactor on the three mounting posts on the upper right side of the chassis,
above the Regulator board. Fasten the Reversing Contactor in place with the three mounting screws
supplied with the kit.
Step 6. Route the red/yellow twisted pair wires (from the current feedback transformer) to the right of the
Reversing Contactor. These wires are connected to the upper right of the drive’s regulator board at
pins 192 and 193 (
IFDBK ).
Step 7. Connect wire harness 45/47 from the Reversing Contactor’s normally open ( NO ) contacts to the
corresponding normally open ( NO ) contacts on the drive’s M-contactor as shown in figure 1.

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, L1/181 and L2/182. 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.
