2 Field Supply Kit for Non-Regenerative and Regenerative FlexPak Plus DC Drives
Installing the Field Supply in a Non-Regenerative FlexPak Plus Drive
Important: This procedure is for non-regenerative FlexPak Plus drives. See page 4 for instructions for
installation into regenerative FlexPak Plus drives.
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 terminal block (1TB) and the terminal block labeled “32/132” from the terminal
block support bracket inside the drive. Leave the wires connected to the terminals.
Step 6. Remove the terminal block support bracket from the drive.
Step 7. Mount the Field Supply support bracket (with the Field Supply power cube and terminal block 2TB) in
place of the terminal block support bracket.
Step 8. Remount terminal block 1TB (removed in step 5) on the left side of the Field Supply support bracket.
Step 9. Disconnect the two wires from old terminal block 32/132. Connect them to terminals 32 and 132,
respectively, on new terminal block 2TB, as shown in figure 1 (full-wave supplies) and figure 2
(half-wave supplies). Discard the old terminal block.
Step 10. Connect wire harness 51/52 to terminal block 1TB. Connect wires F1 and F2 from the Field Supply to
terminal block 2TB on the Field Supply mounting bracket. Refer to figure 1 or 2.
Step 11. 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.
Step 12. For a full-wave supply, connect the motor field wires to terminals F1 and F2 on Field Supply terminal
block 2TB. See 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 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.
