AINTENANCE

The PowerSure PSA UPS requires very little maintenance. Follow these practices to

prevent problems.

CLEANING 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.
MAINTAINING 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.

BATTERY REPLACEMENT

This UPS is equipped with internal “hot swappable” batteries that the user can replace

without shutting down the UPS or connected loads.

!

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.
• 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 imme-
diately.

• Do not dispose of batteries in a fire. The batteries may explode.
• Dispose of old batteries according to local codes.

NOTE

Caution should be exercised when replacing the batteries because the
load is unprotected from disturbances and power outages during this
procedure.
