Units shipped from October 15, 2018 onwards will have the capability for three-phase sensing for the Emergency Source if Accessory 11BE is installed. The 11BE is either factory-installed or field-installed using Kit 935147. Three-phase sensing will not work for older units and single-phase units even if those have the 11BE installed.
The shipment date, and whether or not the unit has the 11BE, can be confirmed by either the Technical Support or Customer Service using the Serial Number of the unit.
For capable units, the three-phase sensing on the Emergency side can be enabled by setting S1 actuator 9 to ON.
