Battery Test
To test batteries, follow the procedure below.
1. Press the “MENU” button.
2. Select submenu “CONTROL” and press “OK.”
3. Select submenu “MANUAL BATT TEST” and press “OK.”
A single acoustic signal confirms testing and the load will be supplied by the battery.

If the test is successful, the “BATT” LED will extinguish and the UPS will return to “On-Line mode.”
If the UPS detects a battery malfunction, an alarm will be displayed.
Maintenance
Do not use abrasive powder or plastic-dissolving solutions to clean the UPS.
Do not allow liquid to penetrate the interior of the UPS.
Make sure that the air vents on the UPS are not obstructed. Remove dust from the air vents with a vacuum
cleaner.
Clean the outside of the UPS housing by wiping with a dry or a slightly damp cloth.
Storage
For extended storage at an ambient temperature < 77°F (25°C) the batteries should be charged for 5 hours
once every 4 months; at higher storage temperatures it is advised that this period be reduced to two
months.
To charge the batteries while in storage:
1. Connect the UPS to an appropriate source (refer to “Installation” on page 8 for more details).

and Disposal/
Recycling of
Batteries
WARNING:
• Servicing of batteries should be performed or supervised by personnel knowledgeable about
batteries and the required precautions.
• The batteries installed in the UPS and in the external battery cabinets contain electrolyte. Under
normal conditions the containers are dry. A damaged battery may leak electrolyte that can be
dangerous in contact with the skin and cause irritation to the eyes. Should this happen, wash the
affected part with copious amounts of water and seek immediate medical attention.
• When replacing batteries, replace with the same type and number of batteries or battery packs.
• Do not dispose of batteries in a fire. The batteries may explode.
• Do not open or damage the battery cases. Released electrolyte is harmful to the skin and eyes and
may be toxic.
• A battery can present a risk of electrical shock and high short-circuit current. The following
precautions should be observed when working on batteries:
•Remove watches, rings or other metal objects
•Use tools with insulated handles
•Wear rubber gloves and boots
•Do not lay tools or metal parts on top of batteries
•Disconnect charging source prior to connecting or disconnecting battery terminals
The UPS does not require maintenance by the user, however, battery maintenance in recommended in
accordance with IEEE Recommended Practice for Maintenance, Testing and Replacement of
Valve-Regulated Lead-Acid (VRLA) Batteries for Stationary Applications (IEEE Std 1188-1996). When
