Utility Restored, Transferred Back to Utility – Inverter Only Configuration
The XA1 limit switch now opens. Spring tension in the switch mechanism closes the switch to the UTILITY position, and
utility voltage powers the load through the main load lug connections.
As the switch closes to the UTILITY position, the XA1 limit switch changes states. With the switch in UTILITY, voltage is
disconnected from the utility coil. XB1 is connected to the standby coil. This makes the switch ready for the next trans-
fer.
NOTE: The closing coil is always powered by the source it is transferring to.
The switch is ready for the next utility power loss event.
