How long is the UTS’s transfer time while switching between Utility Power and Generator Power?
The UTS will take a minimum of 5 sec after losing utility power to close its relay’s, so as to not back feed generator power back into the Main Electrical panel. This process is performed and verified by the UTS, before it will engage its circuits and begin to pass Generator power to the load. The process is referred to as CPLD or Circuit Protection Load Disconnect and has been UL tested and approved under UL1008.
Why am I unable to set Circuit 1 to UPS, either or Uninterruptible?
Circuit 1 is tasked with powering the Convenience Outlet on the face of the UTS. Since the purpose of the Convenience Outlet is to power the UPS being used as your secondary Back-Up source, it essentially cannot back itself up. Therefore Circuit 1 must be supplied power directly from the generator.
The UTS is marketed as being an Automatic Transfer switch, however I am unable to locate the necessary accessory to make this work.
There has been some concern throughout the industry that consumers may use an Auto-start feature with a portable generator. Portable generators are often kept indoors when not in use and may pose a threat of Carbon Monoxide poisoning if automatically started without the owners knowledge.  As a result, Schneider Electric has opted not to manufacture the Auto-Start kit. For those interested in using the Auto-start function with a statically mounted Generator, please obtain the necessary connection block (5.08MM EURO PLUG 6 POS) and contact Schneider Electric for wiring instructions.

If the UTS circuit board were to fail, what is the expected behavior? Will my circuits have power?

If the panel were to fail, you would have to manually bypass the failed circuit by placing the included fastener in line with the Input and Output of the designated circuit.
