cannot be changed to a different power source while
running. Turn the UPS Off and wait until the fans stop. Apply
input AC power. The UPS will reprogram the phase angle to AC
power. The UPS will reprogram the phase angle to match the
utility, if the utility is 120, 180 or 240 degrees between L1 and L2.
If this does not resolve the issue, contact a qualified electrician to
verify the site wiring.
