COMMUNICATIONS
The PowerSure PST has a USB interface port for communication that will work with the built-in Microsoft
Power Manager software on the user’s PC, if the PC is so equipped. It will provide UPS status and manages the automatic, orderly shutdown of the computer. The UPS (USB) communications meets HID standard, version 1.11. All USB models are compatible with Microsoft Windows 2000, Windows XP and Mac
OS 10.2 or later. All USB models ship with a 6 ft. (1.8m) USB cable.

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.
TROUBLESHOOTING CHART
If the UPS fails to operate properly, turn off the unit and repeat
the steps in the Installation section of this manual. If the prob-
lem persists, refer to the chart below:
