Off mode turns off the output and most internal circuitry. Within this mode, another mode (Sleep) turns off all
internal circuitry when AC line is not present and battery voltage drops to a low threshold. If the Battery
Protect (BP) function is selected and input AC voltage is not present, the UPS goes into Sleep mode
immediately when the UPS is turned off. When input AC voltage returns, the UPS automatically recovers from
Sleep mode and, if the Autorestart parameter is enabled, switches to Double Conversion. Autorestart is enabled
as a factory default.
Figure 3 shows the basic functional elements of the UPS.
203 Operator Control Panel
The operator control panel has an alphanumeric display, three LED indicators, and six pushbuttons as described
in Figure 4 and in Table 1.

equipment to the UPS.
