CONNECTING LIST 60 CONVERTER OUTPUT JUMPERS
Note: If List 60 is not provided, skip this procedure.
Note: If the power system was ordered in a relay rack, this procedure has been
performed at the factory.
Procedure
1) Locate the output jumpers (labeled -48V) supplied with List 60 (P/O kit P/N
540860). There are two (2) cables per List 60.
2) Open the distribution cabinet’s front door by turning the latch in the
counterclockwise position.
3) Loosen the (2) screws holding the plastic shield over the circuit breakers or
fuseholders on the dual voltage distribution panel. Slide the shield upwards and
remove.
4) Connect the output jumpers to the distribution bus panel subsystem (-48V) input
terminals as shown in Figure 4-12. Apply electrical anti-oxidizing compound to
lug mating surfaces before connecting. Mount two lugs back-to-back per
mounting position if required. Torque as shown in the figure.
5) Route the output jumpers installed in the previous step over the top of the
distribution bus panel ground bar, toward the back of the cabinet, and down
through the opening in the bottom of the distribution cabinet (between the cabinet
main busbars).
6) Route the output jumpers to the converter output terminals as shown in Figure
4-12.
7) Connect the output jumpers to the converter output terminals as shown in Figure
4-12. Apply electrical anti-oxidizing compound to lug mating surfaces before
connecting. Torque as shown in the figure.
8) Install the plastic shield that was removed in a previous step, over the circuit
breakers or fuseholders. To do so, position the shield and slide downwards on
screws. Tighten screws.
