Maintenance

10.0MAINTENANCE

The PowerSure PSI UPS requires very little maintenance. Follow these practices to prevent prob- lems.

10.1Cleaning the UPS

The following will help ensure trouble-free operation for years:

•Vacuum dust from the ventilation intake occasionally.

•Wipe the cover periodically with a dry cloth.

10.2Maintaining Batteries

The batteries are valve-regulated, nonspillable, lead acid and must be kept charged to retain their design life. The UPS continuously charges the batteries when connected to the utility supply, even while the UPS is switched Off.

When storing the UPS, it is recommended to plug in the UPS for at least 24 hours every four to six months to ensure full recharge of the batteries.

10.3Battery Replacement

! CAUTION

A battery can present a risk of electrical shock and high short circuit current. The following precautions should be observed before replacing the batteries:

•Remove rings, watches, and other metal objects.

•Use a Phillips (crosshead) screwdriver with insulated grips.

•Do not lay tools or other metal objects on top of the batteries.

•If the battery replacement kit is damaged in any way or shows signs of leakage, contact your local dealer or Liebert representative immediately.

•Do not dispose of batteries in a fire. The batteries may explode.

•Dispose of old batteries according to local codes.

NOTE

This UPS is equipped with internal “hot swappable” batteries that the user can replace without shutting down the UPS or connected loads. Caution should be exercised when replacing the batteries because the load is unprotected from disturbances and power outages during this procedure.
