f. Using access from the left side of the enclosure, locate the three (3)
power wires coming from the back of the capacitor bank assembly that
are attached to the inductors. Remove the hex nuts securing the power
wires to the inductors. Retain the hardware.
g. Disconnect the ground wire from the 1 μF Capacitor.
h. If the existing capacitor bank assembly has a surge trap (SPD) device
mounted on the assembly, disconnect the ground wire.
i. Remove the hardware that is securing the capacitor bank assembly to
the mounting panel and carefully remove the capacitor bank assembly
from the enclosure. Once removed, remove the hardware that is
securing the three (3) power wires (see
Figure 2 ) to the back of the
capacitor bank assembly. Retain the hardware.
j. Remove the front four (4) bolts that are securing the top of the
capacitor bank mounting panel to the fiberglass insulator panel (see
Figure 2 ). Retain the hardware.
k. Remove the remaining hardware that is securing the capacitor bank
mounting panel in the enclosure (see Figure 2 ). Retain the hardware
(6x).
