2 Field Supply Kit for Non-Regenerative MinPak Plus DC Drives
Installing the Field Supply
Refer to your MinPak Plus DC drive instruction manual to locate and identify drive components. To install the
Field Supply kit 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 and verify that no voltage is present at the drive’s AC input terminals, L1/181
and L2/182.
Step 3. Mount the Field Supply’s auxiliary mounting bracket as described in instruction manual D2-3379.
Step 4. Connect wire harness 51/52 fromthe Field Supply power cube to terminal block 2TB, located at the
upper left corner of the drive. Verify that wires F1 and F2 are connected from the Field Supply to
terminal block 3TB on the Field Supply mounting bracket.
Step 5. Route the user-supplied motor field wires (F1, F2) into the drive chassis using 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 6. For a full-wave supply, connect the motor field wires to terminals F1 and F2 on Field Supply terminal
block 3TB. See figure 1.
For a half wave supply, connect motor lead F1 to terminal 51 on 2TB and motor lead F2 to terminal
F2 on 3TB. See figure 2.
Refer to the motor’s nameplate label and the technical specifications at the end of this instruction
manual to determine the appropriate field type required.

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.
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
