Eaton Uninterruptible Power Supply 9SX1500

DO NOT DISCONNECT the batteries while the UPS is in Battery mode.

Batteries can be replaced easily without turning off the UPS or disconnecting the load.

If you prefer to remove input power to change the batteries, see "UPS Shutdown" on page 27.

Consider all warnings, cautions, and notes before replacing batteries.

- Servicing should be performed by qualified service personnel knowledgeable of batteries and required precautions. Keep unauthorized personnel away from batteries.

- Batteries can present a risk of electrical shock or burn from high short circuit current. Observe the following precautions:

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.

The EBM is heavy (see page 8), handling requires a minimum of 2 people.

1. Unplug the EBM power cable and battery detection cable from the UPS.

If additional EBM(s) are installed, unplug the EBM power cable and battery detection cable from each EBM.

2. Replace the EBM(s). See "Recycling the used equipment" on page 33 for proper disposal.

Info: A small amount of arcing may occur when connecting an EBM to the UPS. This is normal and will not harm personnel. Insert the EBM cable into the UPS battery connector quickly and firmly.

3. Plug the EBM cable(s) into the battery connector(s). Up to four EBMs may be connected to the UPS.

4. Verify that the EBM connections are tight and that adequate bend radius and strain relief exist for each cable.

5. Connect the battery detection cable(s) to the connector of the UPS and of the EBM(s).
