Maintenance

9.0MAINTENANCE

The UPStation GXT 2U requires very little maintenance. The batter- ies are valve-regulated, nonspillable, flame retardant, lead acid, and should be kept charged to obtain their designed life. The UPS continu- ously charges the batteries when connected to the utility supply.

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

The UPStation GXT 2U is designed to allow the user to safely replace the internal batteries. Read the safety cautions before proceeding. Contact your local dealer or Liebert representative to obtain the appropriate replacement battery kit part number and pricing.

9.1 BATTERY 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, or other metal objects.

Use a Phillips (crosshead) screwdriver with insulated grips.

Do not lay tools or other metal objects on top of the batter- ies.

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.
