F06. Relay Welding. Internal problem. Call Customer support is what APC says in their manual.

One of the internal relays has stuck contacts. Could be the contacts are welded, electronics driving a relay has a problem, electronics that sense the relays position has a problem.

If you do a web search. Lets say for APC F06 error. You will find added information on an F06 error.
