Step 6: Remove Existing
Mounting Brackets
and Install New Kit
Brackets
a. Starting on the left side of the drive, remove the hardware that is
securing the contactor assembly to the mounting bracket (see Figure 3 ).
Retain the hardware (2x).
b. Remove the hardware that is securing the mounting bracket to the
frame of the enclosure (see Figure 3 ). Discard the hardware.
c. Remove and discard the mounting bracket.
d. Install the new mounting bracket and re-use the hardware removed in
Step 6-b. Tighten only to finger-tight until both new brackets are
installed (see
Figure 4 ).
e. Use three (3) M5 x13 pan head screws (supplied with kit) to attach the
new mounting bracket to the enclosure frame (see Figure 4 ).
f. On the right side of the drive, remove the hardware that is securing the
contactor assembly to the mounting bracket (see Figure 3 ). Retain the
hardware.
g. Remove the hardware that is securing the mounting bracket to the
frame of the enclosure (see Figure 3 ). Discard the hardware.
h. Lift the right side bracket vertically then pull the bottom forward to
remove the mounting bracket and discard.
i. Install the new mounting bracket to the contactor assembly by re-using
the hardware removed in Step 6-b. Tighten only to finger-tight until
both new brackets are installed (see
Figure 4 ).
j. Use three (3) M5 x13 pan head screws (supplied with kit) to attach the
new mounting bracket to the enclosure frame (see Figure 4 ).
k. Fully tighten all hardware.
l. Locate the upper capacitor bank mounting bracket (see
Figure 5 ).
Attach the 1 μF Capacitor to the top of the upper cap bank mounting
bracket using two (2) M5 x 10 hex head screws (supplied with kit).
Insure that the ground lead with the ring lug is on the right hand side.
m. Re-use the hardware removed in Step 5-j to attach the upper capacitor
bank mounting bracket to the fiberglass insulator panel.
n. Using four (4) M6 x 16 hex head bolts and four (4) channel nuts
(supplied with kit), attach the upper capacitor bank mounting bracket
to the vertical channels of the enclosure. Use the upper left bolt to
attach the ground lead from the 1 μF Capacitor (see
Figure 5 ).
o. Attach the lower capacitor bank mounting bracket using the four (4)
M6 x 16 hex head bolts and four (4) channel nuts (supplied with kit) to
the vertical channels of the enclosure (see
Figure 5 ).
p. Attach the Bleeder Resistor to the lower capacitor bank mounting
bracket using the twelve (12) M3 x 8 pan head screws (supplied with
kit). Use wire ties to properly secure the Bleeder Resistor wires.
ATTENTION: Upon removing and installing the mounting brackets and
hardware, sharp edges may be encountered. Use work gloves to protect your
hands.
