6.0 Operating Instructions
1. Output Connector:
The output connector will provide protection from surges
and power failures to the critical loads.
2. Switch ON Green Mode Enabled:
After connecting the UPS to the utility
power, press the ON button until you hear the first beep, then release the
button immediately. The Green Mode is enabled, i.e. if a load less than forty
watts (or no load) is connected and the UPS operates in the Backup Mode.
The UPS will enter into the Green Mode status after three minutes of backup
time; the green light will flash every three to five seconds and after a short
period of time; and the unit will enter a “power save” status by shutting down
to prevent deep discharge of the battery. To reactivate the unit, power the unit
OFF then ON again or reapply utility power.
3. Switch ON Green Mode Disabled:
After connecting the UPS to the utility
power, press the ON button and keep pressing it until you hear two short
beeps “Bi-Bip”, then release the button immediately. The Green Mode is now
disabled. Any kind of load, whether smaller than forty watts or larger, will not
affect the normal operation of the UPS under Ac or Battery Mode.
4. Switch OFF:
To switch OFF the UPS, press and hold the Power ON/OFF/Test
button until the “Ac Power Normal” LED or “ON Battery” LED turns OFF.
