Step 7: Install the New
Filter Capacitor
Assembly
a. Before installing the new capacitor bank assembly, attach the power
wires to the back of the capacitor bank assembly using the hardware
removed in Step 5-i (see
). Connect Rockwell Automation
power wire PN-109106 to the Bus Bar labeled FU-4, Rockwell
Automation power wire PN-109107 to the Bus Bar labeled FU-5, and
the remaining Rockwell Automation power wire PN-109107 to the Bus
Bar labeled FU-6. Tighten to 45…50 lb•in (5.1…5.6 N•m).
b. Place the new capacitor bank assembly in the enclosure and hang it
from the three (3) studs on the upper capacitor bank mounting bracket
(see
c. Using three (3) M6 hex nuts (supplied with kit), secure the top of the
capacitor bank assembly in place. Tighten only to finger-tight until the
remaining hardware is in place (see
d. Secure the bottom of the capacitor bank assembly with three (3) bolts
).
e. Tighten all hardware installed in Step 7-c and Step 7-d.
f. Using access from the left side and the hardware removed in Step 5-e,
secure the power wire coming from FU-6 to the right hand inductor
connection, the power wire coming from FU-5 to the center inductor
connection, and the power wire coming from FU-4 to the left hand
inductor connection (see
). Tighten to 30…35 lb•ft
(40.7…47.5 N•m).
g. Connect the free lead from the 1 μF Capacitor to the terminal on the
capacitor bank assembly.
h. Insure that the surge trap style SPD, shown in the “Precheck”
section on
, is installed and reconnected properly.
