BA Drive Package

The standard package includes the heat sink, cover, shunt regulator, and the bus power
supply, which operates from 56-230 VAC depending on the model (see section 3.1 for
ordering instructions). The power supply is included with the standard package for
off-line operation without the need for an isolation transformer. Figure 1-2 is a functional
diagram showing the standard package configuration.
