Your UPS is equipped with an LED indicator display to keep you alert to its effectiveness.This surge protection indica- tor light is illuminated when the surge protection components are functioning properly. If this light is off, it indicates that the surge protection components have reached capacity and are no longer able to protect your connected equipment against surges.

Your UPS also offers a “ground” indica- tor light to confirm that the wall outlet is wired properly.

Auto restart

Your UPS is equipped with an auto shut down feature which activates when the battery level becomes too low to sustain power to your connected equipment and electricity is not present.

For example, if you are away from home during a power outage, your UPS will im- mediately provide power to your connect- ed equipment through its internal battery. If the power outage exceeds the runtime of the UPS, the UPS will automatically switch into Suspend Mode, ceasing power to your connected equipment. It will retain the little power it has remaining to ensure that, when the power does return, it is

safe to channel to your equipment. Once the power returns, the UPS will automati- cally reset itself to normal operation and recharge its internal battery.

Back-up alarm

In the event of a power failure, your UPS will sound an alarm, alerting you that it is going into back-up mode. It will sustain this alarm, beeping slowly every two seconds.

To mute the alarm:

1.Press the power button for one second and release.

Warning

Do not hold the power button down for more than 1 second when muting the alarm. Holding the power button down 3 seconds or longer will turn the UPS completely off, halting battery power to your connected equipment.

Low battery alarm

When your UPS has been in back-up mode for an extended time and its internal battery has been depleted down to 20% or 30% of its power, it will sound an alarm, beeping rapidly every half second.This alarm will continue until the UPS shuts down completely from battery exhaustion or it automatically returns to normal (LINE) operation.

Rotating LCD display

Your UPS may be positioned either hori- zontally or vertically. If you choose to use it in a vertical position, you will have to adjust the LCD panel from a horizontal to vertical position.
