Reading the users manual... pp 33, "Setting Power Strategy", it
indicates that normal operation is true online (as above) and that you
can change it to "high efficiency" mode, which is not online per se
(default bypass, 10 ms cutover if it detects a fail or spike).  So it
has 3 modes; default/normal (online), high efficiency (bypass
w/cutback), and partially failed (bypass only, UPS functions
disabled).
