Plants
A multiple-shelf CPS plant is composed of:
• an initial shelf, which provides for:
– rectifiers
– converters or ringing generators
– a control unit
– an LVD contactor (see Note below)
– associated control and temperature compensation circuits
– output bus bars, which are used to interconnect the shelves and
connect the batteries
• one or two supplemental shelves, each of which provides for:
– rectifiers
– converters or ringing generators
– output bus bars, which provide terminations for the plant’s
primary output
Note: The initial shelf must be installed as the top or bottom shelf in a
three-shelf system.
Note
The LVD disconnect/reconnect feature is not available for
multiple shelf plants with N + 1 loads greater than 150
amperes.
