System Enable Switch (DIP Switch #4)

This switch is located in the set of 4 switches next to the UPS’s DB9 ports. It activates the battery charger and intelligent microproces- sor. Always leave it in the “ENABLE” (UP) position when your UPS is plugged in. Set the switch to “DISABLE” (DOWN) only if you store or ship your UPS (to reduce battery drain).

Note: the “ ” light will flash until you engage the ON/Standby Switch to activate the “ON” mode (power ON at the UPS receptacles).
