Switches
System Enable Switch*
This switch activates the battery charger and intelligent
microprocessor. Always leave it in the “ENABLE” position
when your UPS is plugged in. Set the switch to “DISABLE”
only if you store or ship your UPS (to reduce battery drain).
*Note: the location of the switch varies by model. The “XXX” light will flash until you engage the
ON/Standby Switch to activate the “ON” mode (power ON at the UPS receptacles).

*** If you do not connect a computer to either of the “BASIC” DB9 ports, set their corresponding LAN Interface DIP Switches to the
DEACTIVATE (RIGHT) position. Note: DIP Switch #3 has no function.
