option)
3.4. Rectifier Shelf and Module Installation
Since expandability is so important, rectifiers and rectifier shelves are very easy to install. A
rectifier shelf will hold up to 3 rectifiers. There is individual ac input wiring for each rectifier.
Each rectifier will communicate to the controller through a ten-pin ribbon cable.
WARNING: Ensure that all of the ac circuit breakers for any rectifier shelf
to be added are in the OFF position prior to installing the additional shelf/
shelves.
