3Ø, 600 VAC can be achieved via the auto-transformer
module. This module provides the necessary electronics
to convert the 3Ø, 480 VAC inut voltage to a 3Ø, 600 VAC
output voltage.
The 3Ø, 600 VAC ouput voltage cannot be achieved unless
the voltage selector switch (Figure 29) is placed in the 3Ø,
480/277 position.
