4 AC Line Disconnect Kit for FlexPak 3000 and WebPak 3000 Drives
Installing the AC Line Disconnect on Drives in a NEMA 1 Enclosure
Step 1. Turn off, lockout, and tag power to the drive.
Step 2. Remove the cover from the drive.
Step 3. Disconnect the input AC power line connections to the drive’s terminal block as shown in figure 2A.
Step 4. Remove the existing wiring between the terminal block and fuses as shown in figure 2A.
Step 5. Remove the terminal block by removing the two screws holding it in place as shown in figure 2A.
Step 6. Attach the label (Item 2) to the AC Line Disconnect (Item 1) as shown in figure 3C.
Step 7. If the AC Line Disconnect (Item 1) is to be used as the drive’s main disconnect, affix a "MAIN" label
(user supplied) to the front of the AC Line Disconnect. Do not cover any AC Line Disconnect mounting
screw holes when applying the label.
Step 8. Install the AC Line Disconnect (Item 1) on the drive’s molded fuse block using the following procedure
(see figures 3A and 3B).
a. Position a standoff bracket (Item 10) on the drive’s molded fuse block and mount it using four M4
x 12 screws (Item 5) as shown in figure 3B. Repeat this step to install the remaining standoff
bracket.
b. Position the AC Line Disconnect on the standoff brackets.0.
c. Mount the AC Line Disconnect to the brackets (attaching the right and left lock hardware (Items 3
and 4) at the same time) using four M4 x 90 screws (Item 7), flat washers (Item 11), and M4 nuts
(Item 8). See figure 3B.
Step 9. Attach the wire assemblies (Items 13, 14 and 15) between AC Line Disconnect terminals 181, 182
and 183 and the corresponding line fuse terminals. (For example, connect AC Line Disconnect
terminal 181 to line fuse terminal 181.)
Use the three 1/4 - 20 x 5/8 RHMS bolts (Item 17) and the three 1/4 slit washers (Item 16) to attach the
wire harnesses to the AC Line Disconnect.
Use the three M6 Nut/washers (Item 9) to attach the wire harnesses to the line fuse terminals.
See figure 3B for the location of the AC Line Disconnect terminals and the line fuse terminals. See
figure 3C for an illustration of the installed wire assemblies.
Step 10. Torque the nuts on AC Line Disconnect terminals and the line fuse terminals to 55 in-lb (6.2 Nm).

ATTENTION: Do not install modification kits with power applied to the drive. Disconnect and lock
out incoming power before attempting such installation. Failure to observe this precaution could
result in severe bodily injury or loss of life.
