Interconnecting the Rectifier Module Mounting Shelves Output Busbars in Multiple Shelf Systems
NOTE!
as this procedure is performed.
Procedure
1.
The mating busbars are factory installed on the expansion rectifier module mounting shelf. Secure
these busbars to the output busbars on the shelf above it. Hardware is provided with the expansion
rectifier module mounting shelf.
Hardware build-up for these connections is:
1/4-20 x 7/8" Bolt,
1/4" Belleville Lock Washer,

NOTE!
Some systems may come with two shelves connected together with a common relay rack
mounting bracket and an output busbar spanning both shelves. Connect these shelves to other shelves
in the same manner as described here.
2.
Repeat this procedure for each expansion rectifier module mounting shelf.
