Normal Mode
During Normal mode operation, the PowerSure PSP supplies condi-
tioned, computer-grade power to the connected equipment: utility
power passes through the EMI/RFI filters and TVSS circuitry and
then through the Transfer Switch to the connected equipment.
When the UPS is in Normal mode, the Utility Indicator illuminates
green.
The PowerSure PSP continuously monitors the batteries to maintain
them in a fully charged state. The battery charger operates whenever
AC power is present, even if the UPS is switched off. By default, the
UPS is set to perform an automatic battery test after it has been oper-
ating continuously for two (2) weeks. The interval at which the UPS
performs a battery test can be configured via MultiLink.
