Automatic Retransfer

When the preferred inlet's power quality restores to the normal level, an
automatic retransfer from the alternate back to the preferred inlet occurs.
The automatic retransfer is not performed if:
•
Automatic retransfer is disabled.
•
Inlets are out of phase.
Tip: To disable the inlet phase synchronization requirement, see
Switch (on page 193) or
(on page 118).
