Does the DOL58 need an additional power supply?

As per the AutoFlex Connect and DOL58 user manuals, the DOL58 requires connection to the IN-4, as well as a separate 11-30vdc power supply. This could be a standalone 12vdc or 24vdc power supply, or, you can use the 12vdc terminal on the backboard of the AutoFlex Connect.
