Page 27

To replace the component, reverse the removal procedure.

CAUTION: Only one communications port can be connected to the host computer. Connecting more than one will result in unexpected UPS behavior. If an option card is installed, the serial and USB communications ports are automatically disabled.

NOTE: Replacing the option card might require power management software to be restarted or reconfigured.

Replacing the batteries

To replace the batteries:

1.Read and observe the requirements in "Important battery safety information" and "Battery care and storage guidelines (on page 27)."

2.Follow the instructions in "UPS battery replacement procedure (on page 28)."

Important battery safety information

WARNING: The unit contains sealed lead-acid battery modules. To prevent fire or chemical burns:

•Do not attempt to recharge batteries after removal from the unit.

•Do not disassemble, crush, or puncture the batteries.

•Do not short the external contacts of the batteries.

•Do not immerse the batteries in water.

•Do not expose to temperatures higher than 60°C (140°F).

WARNING: To prevent personal injury from hazardous energy:

•Remove watches, rings, or other metal objects.

•Use tools with insulated handles.

•Do not place tools or metal parts on top of batteries.

NOTE: Replace all battery modules at the same time.

Battery care and storage guidelines

CAUTION: Because of the short shelf life of the batteries, avoid storing a battery spare as a backup. Do not maintain an inventory of spare batteries on site unless a procedure to keep these batteries charged while in storage is implemented.

To maintain the batteries:

•Minimize the amount of time the UPS uses battery power by matching the UPS configuration with the utility voltage. See "Selecting the UPS voltage configuration (on page 19)."

•Keep the area around the UPS clean and dust-free. If the environment is very dusty, clean the outside of the UPS regularly with a vacuum cleaner.
