I. Installation

Follow the installation illustration on the accompanying sheet.

Note: Small sparks at the battery connectors are normal during connection.

II.Post-Installation

Once installed,

allow the unit to charge for five hours. If the unit is an XL model, allow it to charge for

24 hours.

Note: The Smart-UPS will charge whether it is on or off, and will charge whether there is a load present or not. In situations where the power quality is poor, it is recommended that the unit be shutdown during this charging period. A Smart-UPS that is powered on may switch to battery operation which would prolong the time needed to fully recharge the battery.

III. Clearing the Replace Battery LED

A.In order for the replace battery LED to be cleared, it is necessary to run a valid self test. For a self test to be considered valid, the following conditions must be satisfied:

■battery capacity must be greater than 75%(minimum of four battery bar graph LEDs illuminated) or

■Smart-UPS must have been charging for at least 8 hours from the last low battery condition. (Low battery condition refers to a state when the Smart-UPS battery has fully discharged).

B.Ways to initiate a self test

A self test can be initiated in any one of five ways:

■Start up of the UPS

■Smart-UPS front panel test button

■Powerchute PLUS software

■SmartSlot Accessory

■ Automatic timer- every two weeks from turn on (see APC owners manuals for details)

IV. Verifying Operation

A.What happens during a self test?

When a self test is initiated, the unit supports the load while operating on battery for approximately 8-10 seconds. During this period, the Smart-UPS determines the health of the battery.

B.When should the self test be performed?

After the unit has charged for five hours, a self test can be performed.
