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).

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

40

)."

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.

a.

Connect the UPS to utility power.

b.

Allow the UPS to remain in Standby mode.

c.

Allow the UPS to charge the batteries for at least 24 hours.

d.

Update the battery recharge date label.

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

41

)."

For the location of LEDs, see "UPS front panel LED indicators (on page

8

)."

Obtaining new batteries

New batteries might be required within 30 to 60 days when the Battery Fault LED illuminates red. Obtain
spare batteries for the UPS when this occurs.
Spare battery modules are available for this UPS. The UPS spare battery kit part number is 517703-001.
