in this section. Move the assembly out of the way to the
left.
2. Disconnect the lead from the inner tab of L4.
3. Remove the other (outer tab) lead (coming from L4) from
its connection point on the bus bar assembly.
4. While supporting the weight of L4, remove all four of the
mounting nuts that secure it to the rear wall. Remove L4.
DC Capacitors
(C1, C2, or
C3/C4)
1. Remove Cables A and C from the bus bar assembly (refer
to Figure 5-3).
2. Remove the cable from the inner tab of L3.
3. Remove the heat sink common cable from the top of the
heat sink.
4. For the dc capacitor and bus bar assemblies, remove both
of the nuts from the rear wall studs and the nuts from the
studs on the right side wall of the frame. Remove the unit
to access the individual capacitors.
5. To remove any individual capacitor, remove the two
terminal screws that hold the capacitor to the dc capacitor
and bus bar assembly. Note that C1 is the rear-most
capacitor, C2 is the middle capacitor, and C3/C4 is the
front-most capacitor (before assembly is dismounted).
DANGER
DC capacitors may be charged even with power disconnected
from the rectifier. This would be true if the main bus bar fuses
are open. Always check all of the dc capacitor terminals
(observe polarity) with a voltmeter before performing this
procedure, and discharge capacitors in a safe manner, if
necessary.
