Replacing Batteries
Our hot-swappable battery feature allows you to replace your UPS
batteries easily without turning the UPS off or disconnecting the load.
The following section explains how.
When to Replace Batteries
When the Battery Service LED (LED 10) turns red, your batteries may
need replacing. Conduct a self-test by pressing the
Test/Alarm Reset button. If the LED stays on, contact your service
representative to order new batteries.
WARNING
œ
ELECTRIC ENERGY HAZARD. Do not attempt to alter wiring in either the battery connector or the battery
tray. Attempting to alter wiring can cause injury or death.
œ
A battery can present a risk of high short circuit current which can cause burns. The following precautions
should be observed when working on batteries: 1) Remove watches, rings, or other metal objects;
2) Use tools with insulated handles; 3) Do not lay tools or metal parts on top of batteries.
œ
The battery has no support when you pull it out of the UPS. Pull the battery out onto a flat, stable
surface.
