4 Field Supply Kit for Non-Regenerative and Regenerative FlexPak Plus DC Drives
Installing the Field Supply in a Regenerative FlexPak Plus Drive
Important: This procedure is for regenerative FlexPak Plus drives. See page 2 for instructions for installation
into non-regenerative FlexPak Plus drives.
The Field Supply kit is shipped as an assembly mounted on a support bracket. For installation in a FlexPak
Plus regenerative drive, kit components must be removed from the support bracket and mounted internally in
the FlexPak drive.
Refer to the wiring diagram included with the kit and to your FlexPak Plus drive instruction manual for help
locating and identifying drive components.
To install the Field Supply kit:
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 and L2.
Step 4. Remove and set aside the drive’s auxiliary mounting bracket.
Step 5. Remove the power cube and terminal block 2TB from the Field Supply kit support bracket. Do not
disconnect the jumpers.
Step 6. Remove the drive terminal block labeled “32/132” from the drive. Save the fasteners. Note the
connections to old terminals 32 and 132. Reconnect these to the new terminal block, 2TB, removed in
step 5. Discard terminal block “32/132”.
Step 7. Mount the field supply power cube between terminal blocks 1TB and 2TB. Use the 6-32 x 3/4 screw
and the nylon washer to mount it on the U-bar in the center of the drive chassis.
Step 8. Connect wire harness 51/52 to terminal block 1TB. Connect wires F1 and F2 from the Field Supply to
terminal block 2TB. Refer to figure 3 (full-wave supplies) or figure 4 (half-wave supplies). Use the
fasteners removed in step 6 to mount terminal block 2TB to the drive where terminal block “32/132”
was previously mounted.
Step 9. Route the user-supplied motor field wires (F1 and F2) into the drive chassis. You can use the same
conduit as the armature and motor thermostat conductors. Refer to the section on DC wiring in your
MinPak Plus DC drive instruction manual.

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.
ATTENTION: This kit contains ESD (Electrostatic Discharge) sensitive parts and assemblies.
Static control precautions are required when installing, testing, servicing, or repairing this
assembly. Failure to observe these precautions could result in damage to, or destruction of, the
equipment.
