- From
the
Series Inductor
column of table 3-3,
determine the taps of inductors A9L1 and A9L2
that are to be interconnected.
- From
the
Parallel Inductor
column of table 3-3,
determine the tap of L4 that is to be connected
to L3-1 and the tap of L3 that is to be connected
to L4-1.
- From
the
Series Capacitors
column of table 3-3,
determine the number of capacitors that are to
be placed in-circuit by capacitor selector plate
E1.
- From
the
Parallel Capacitors
column of table 3-
4, determine the number of capacitors that are to
be placed in-circuit by capacitor selector plate
E2.
(d) Interconnect the taps of series inductors L1 and
L2 as identified in step (c).
(e) Interconnect the taps of parallel inductors L3
and L4 as identified in step (c).
(f) Position series capacitor selector plate E1 over
capacitors C1, C2, C3 and C4 so it places, in-
circuit, the number of capacitors identified in
step (c).
Change position of capacitor selector plates by
removing any screws attaching plate to a capacitor,
loosen nut in centre of plate and then carefully
rotate plate to the desired orientation. An insulating
pad is located directly under selector plates E1 and
E2. Ensure pad is correctly positioned and then
secure plate to each in-circuit capacitor. Tighten
bolt in centre of selector plate.
(g) Position parallel capacitor selector plate E2 over
capacitors C5, C6, C7 and C8 so it places, in
circuit, the number of capacitors identified in
step (c).
(h) Reinstall rear panel on harmonic filter assembly
removed in step (b). Ensure hardware is
fastened securely.
