Remote Monitoring

Alarm Signal Contacts: These are relay contacts (rated at 25 Vac/Vdc and 250 mA) that change status on any alarm condition or when the UPS is turned off. Contacts that close on an alarm are available between Pins 23 and 24. Contacts that open on an alarm are available between Pins 24 and 25.

Inverter On Signal Contacts: These are relay contacts (rated at 25 Vac/Vdc and 250 mA) that change status when the inverter turns on. Contacts that close on inverter operation are available between Pins 12 and 13. Contacts that open on inverter operation are available between Pins 11 and 13.

NOTE FE 500 VA–3.1 kVA models with serial numbers 25000 and greater have equivalently rated DC solid state switches.

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; do not use Pin 14.) Use a shielded, single twisted-pair cable to 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.”
