Connecting Pressure Lugs to the Output Power Terminals

Step 1. Attach a pressure lug (item 8) to each output power terminal (terminals U, V, and W) using the

supplied fasteners. Place a 3/8 -16 UNC x 1.50” hex head screw, 3/8” flat washer, and a 3/8“ split ring
lock washer (items 14, 15, and 16) through the lug and the hole in the power output terminal and
fasten with a 3/8” flat washer and 3/8-16 UNC nut (items 15 and 17).

Step 2. Torque the three hex head screws to between 30 to 32 ft-lb (42 to 44 N-m).

Installing the Coolant Input and Output Hoses

Note: Lay the drive on its back to provide easier access to the coolant inlet and outlet.

Step 1. Locate the plastic shield at the bottom of the drive. Loosen and remove the three M4 screws that hold

the shield in place. Remove the shield. Save the screws.

Step 2. Install the coolant input hose and output hose.

Step 3. Reinstall the plastic shield using the original M4 screws. Torque the screws to between 11 to 13 in-lb

(1.2 to 1.5 N-m).

Important: You may want to mount the drive before installing the reactor cooling fan and the printed circuit

board cover. Follow the instructions in the LiquiFlo Hardware Reference manual (D2-3411) to
mount the drive.

Installing the Reactor Cooling Fan

Step 1. Drill two .223” holes through the mounting panel. Refer to figure 1 for hole locations.

Step 2. Fasten the fan assembly to the panel using two 1/4-20 x 1/2” thread rolling screws (item 13). Torque

the screws to between 72 to 76 in-lb (8.3 to 8.6 N-m).

Step 3. Make the electrical connection to the two solder terminals on the fan assembly (item 7).

Installing the Printed Circuit Board Cover

Step 1. Loosen, but do not remove, the top two M5 machine screws that hold the drive front panel.

Step 2. Remove the other six M5 machine screws. Save the screws.

Step 3. Install the printed circuit board cover (item 4) by locating the keyholes in the cover over the top two M5

machine screws.

Step 4. Reinstall all M5 machine screws, and torque all eight screws to between 23 to 28 in-lb (2.7 to

3.1N-m).

This completes the installation of the LiquiFlo panel mount kit.
