CHAPTER 4
Operation
1.Turning The UPS On and Off
Depending on how the UPS was turned off, it may automatically turn on when the input plug is plugged in. If it does not turn on automatically, depress the control button located on the front panel for four seconds until the UPS turns on. To turn the UPS off press and hold the control button for five seconds or until the UPS turns off. UPS batteries will still continue to recharge after the UPS has turned off.
2.UPS Self Test
Depressing the control button for one second while the UPS is turned on will initiate a self test sequence.
3.UPS Overload Condition
To ensure that your computer equipment will be protected during a utility failure, it is important to make sure that the maximum power required from the equipment is not over the rated capacity of the UPS. The LCD overload indicator will be displayed and an audible alarm will sound if the load is over 120% of the UPS's rated output. If the over load is greater than120% , the UPS will shut down immediately to protect the itself. After three seconds, if the overload is removed the UPS will automatically turn on again. If the overload is still present the UPS will turn off and stay off, requiring the UPS be manually restarted. Always correct any overload condition immediately.
4.DC Start, Cold Start
To start the UPS when utility power is not available, press and hold down the control button twice for one second each time. The UPS will start up and run on its internal battery until discharged. If you do not depress the control button to turn the UPS off during battery operation, the UPS will automatically restart when utility voltage is reapplied. The UPS batteries should not be left discharged for long periods of time or battery damage may occur.
Always reconnect the UPS to a utility source, turn the UPS on and allow the batteries to recharge for eight hours after the batteries have been fully discharged due to DC operation.
5.Green Mode Function
The UPS is equipped with a Green mode function. If no load is present at the UPS output receptacles (no equipment connected or the load is less than 25 watts), the UPS will shut down within 12 seconds. Should the utility AC be lost during the shut down, the UPS will automatically restart and again shut down after another two minutes of no load being applied.
