Remote Shutdown

The FERRUPS UPS can be connected to a remote shutdown switch to
shut off output from the UPS to your protected equipment. The
shutdown switch must have a set of contacts that can apply the UPS's
+12 Vdc on Pin 6 to the UPS's Pin 21. (You can use Pin 18 instead of
Pin 6;
connect the switch to the UPS pins. A connection between Pins 6 and 21
(or 18 and 21) shuts down UPS output power to the protected
equipment.
When the UPS Remote Shutdown feature has been activated, the UPS is
in the Off mode and the Emergency Power Off alarm sounds. A control
panel or a terminal connected to the UPS displays "Emergency PwrOff."
