MAINTENANCE
The PowerSure PST 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.
