The DC Connector CAT III rated for use from -60 – 60Vdc. It can measure the
voltage across that full range but if powered by the DC port, there must be at
least 9Vdc. If an installation utilizes both the AC Mains Connector as well as
DC Connector, and DC power is used to power the unit, there must be more than
12Vdc to ensure unit pulls power from the DC port.
