24 hours.

This button controls output power to connected load(s) and has dual functions: OFF 

and Bypass.

Pressing the OFF/Bypass button twice within 4 seconds shuts off power to the output receptacles and 

connected loads, but the UPS’s circuits remain live, charging the unit’s battery.

NOTE
The LOW BATTERY and BYPASS reminder alarms CANNOT be silenced.

Pressing the OFF/Bypass button once will cause the load to be 

transferred to bypass power. Pressing the OFF/Bypass button a second 

time within 4 seconds will result in loss of power to the output 

receptacles and connected loads. Perform all necessary shutdown 

procedures on connected loads before pressing this button twice.
