There are several options to provide AC inputs to the 588705300 module mounting shelf. See PD588705300.
1. For factory installed module mounting shelves without plug-in AC input connectors, AC input leads are factory connected
from the module mounting shelf AC input terminals to an AC input termination assembly provided in the system/cabinet.
Refer to the system/cabinet documentation for connection details to the AC input termination assembly. Refer to the
system/cabinet documentation for recommended AC input branch circuit protection.
2. For a field installed module mounting shelf in a system with a List 27 distribution cabinet or if a List 7 distribution cabinet
system is used in a relay rack and not a system cabinet, the module mounting shelf is equipped with plug-in AC input
connectors located on the rear of the shelf. AC input cable assemblies with mating connectors are available (see Power Data
Sheet PD588705300). Refer to Power Data Sheet PD588705300 for recommended AC input branch circuit protection. See
