Operation BYPASS MODE: BYPASS is an operating mode where the UPS is passing unprocessed input power directly through to the output. BYPASS MODE can engage on an automatic basis (AUTO-BYPASS) as an emergency UPS operating mode that maintains output to connected equipment in case of UPS overload or internal component failure that would otherwise cause connected equipment to lose power. AUTO-BYPASS MODE operation resulting from sudden UPS overload as the UPS is running in ON LINE MODE will automatically reset, once the output load is reduced. BYPASS MODE resulting from internal UPS failure may not automatically reset, and if the message persists, users should contact Tripp Lite for troubleshooting or repair options. Regardless of the cause, the UPS will not provide battery backup anytime the UPS is running in BYPASS MODE. STANDBY MODE: When first connected to a live power source, the UPS will automatically energize in Standby mode and report OFF on the LCD screen. The charger will activate as necessary, but there is no UPS output or battery backup support available in this mode. To turn the UPS on for normal operation, press and hold the ON button until a beep is heard; the UPS will energize after a series of diagnostic tests are completed. To turn the UPS completely off from standby mode, just unplug the UPS from its power source; the UPS will turn OFF and the fan and LCD screen will turn off after approximately 30 seconds.

Operation
BYPASS MODE:
BYPASS is an operating mode where the UPS is passing unprocessed
input power directly through to the output. BYPASS MODE can
engage on an automatic basis (AUTO-BYPASS) as an emergency
UPS operating mode that maintains output to connected equipment
in case of UPS overload or internal component failure that would
otherwise cause connected equipment to lose power. AUTO-BYPASS
MODE operation resulting from sudden UPS overload as the UPS is
running in ON LINE MODE will automatically reset, once the output
load is reduced.
BYPASS MODE resulting from internal UPS failure
may not automatically reset, and if the message persists, users
should contact Tripp Lite for troubleshooting or repair options.
Regardless of the cause, the UPS will not provide battery backup
anytime the UPS is running in BYPASS MODE.
