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.
WARNING: To prevent personal injury, prepare the area and observe all materials-handling
procedures when transporting a battery module. Battery modules weigh 20 kg (44.1 lb).
NOTE: Replace all battery modules at the same time.

Battery care and storage guidelines

•
Minimize the amount of time the UPS uses battery power by matching the UPS configuration with the
utility voltage. Refer to "Configuring the UPS (on page 42)."
•
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.
•
Maintain the ambient temperature at 25°C (77°F).
•
If storing a UPS for an extended period, recharge the batteries every 6 months:
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.
Connect the UPS to utility power.
a.
Allow the UPS to remain in Standby mode.
b.
Allow the UPS to charge the batteries for at least 24 hours.
c.
Update the battery recharge date label.
d.

Determining when to replace batteries

When the Battery Fault LED illuminates, batteries might need to be replaced within 30 to 60 days.
When a battery alarm sounds, initiate a UPS battery self-test to verify that battery replacement is required.
If the Battery Fault LED remains illuminated, replace the batteries as soon as possible.
For more information on initiating a self-test, see "Initiating a self-test (on page 43)."
For the location of LEDs, see "UPS front panel LED indicators (on page 7)."
