UPS Operating Modes
Standby Mode
(Charger: ON / AC Output: OFF / Battery Backup: NOT AVAILABLE)
When first connected to a live power source, the UPS will automatically energize into STANDBY
MODE. In this mode, the UPS charger will function as necessary to maintain full battery charge,
but there will be no AC output and no battery backup for connected equipment in the event of a
power failure. To turn the UPS on into LINE POWER MODE, press and hold the “ON/OFF” button for
one second until a beep is heard, and release.
Line Power Mode
(Charger: ON / AC Output: ON / Battery Backup: AVAILABLE)
The standard protected UPS operating mode for the UPS is LINE POWER MODE. In this mode, the
UPS provides voltage-regulated output sourced directly from the AC mains line power input. UPS
output power is conditioned with automatic voltage regulation in LINE POWER MODE to correct any
voltage fluctuations present on the mains line power input. When operating in LINE POWER MODE,
the UPS will automatically switch to BATTERY MODE during power failures or severe voltage
fluctuations to maintain connected equipment operation from battery reserves.
Battery Mode
(Charger: OFF / AC Output: ON / Battery Backup: ON)
BATTERY MODE is the automatic UPS response to mains AC power failures and severe voltage
fluctuations occurring when the UPS is operating in LINE POWER MODE. In BATTERY MODE, the
UPS is providing battery-derived AC output to connected equipment. When running in BATTERY
MODE, the UPS will automatically return to LINE POWER MODE when acceptable mains AC input is
restored to the UPS.
