The 5-LED display on the left of the front panel represents the power drawn from the UPS as a percentage of total capacity. For example, if three LEDs are lit, the load is drawing between 50% and 67% of the UPS’s capacity. If all five LEDs light, thoroughly test your complete system to make sure that the UPS will not become overloaded.

Overload

When the UPS is overloaded (when the connected loads exceed the maximum specified in the “maximum load” section under Specifications, page 12), the overload LED comes on and the UPS emits a sustained tone. The alarm remains on until the overload is removed. Disconnect nonessential load equipment from the UPS to eliminate the overload.

SmartTrim

The SmartTrim LED comes on to indicate that the UPS is compensating for a high voltage.

SmartBoost

The SmartBoost LED comes on to indicate that the UPS is compensating for a low voltage.

Low Battery

When the UPS is operating on-battery and the energy reserve of the battery runs low, the UPS beeps continuously until the UPS shuts down from battery exhaustion or returns to on-line operation.

Cold Start

When the UPS is off and there is no utility power, use the cold start feature to apply power to the loads from the UPS’s battery.

Note:

Cold start is not a normal condition.

• Press and hold the on/test button until the UPS beeps.

•Release the on/test button during the beep and the loads are powered within four seconds.

Note:

The UPS starts a self-test as a part of this procedure. The self-test does not affect the voltage display. The utility

voltage bar graph has a margin of error of ± 4%.

Storage Conditions

Store the UPS covered and upright in a cool, dry location, with its battery fully charged. Before storing, charge the UPS for at least two hours. Remove any accessories in the accessory slot and disconnect any cables connected to the computer interface port to avoid unnecessarily draining the battery.

Extended storage

At -15 to +30 °C (+5 to +86 °F), charge the UPS’s battery every six months.

At +30 to +45 °C (+86 to +113 °F), charge the UPS’s battery every three months.
