403 Remote Monitoring and Remote Shutdown

Monitoring

Alarm Signal Contacts:

These are relay contacts (rated at 25V AC/DC and 250 mA) that change

status on any alarm condition or when the UPS is turned off. (See the

beginning of Section 400.) 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 25V AC/DC and 250 mA) that change

status when the inverter turns on. (See the beginning of Section 400.)

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.

Remote Shutdown

FERRUPS 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 FERRUPS’ +12 VDC on pin 6 to

FERRUPS’ 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 FERRUPS’ pins. A connection between pins 6 and 21 (or 18 and 21) will shut down

FERRUPS’ output power to the protected equipment. When FERRUPS’ Remote Shutdown feature has been

activated, FERRUPS will be in the Off Mode, and the Emergency Power Off Alarm will sound. A control panel or

a terminal connected to the FERRUPS will display “Emergency PwrOff.” To restart the UPS, break the connection

between pins 6 and 21 (or between pins 18 and 21) at FERRUPS’ RS232 port. Then, follow the steps in the Startup

section for your model (202 or 203). Note that the 12-volt level on pin 6 or pin 18 is only available when

FERRUPS is operating.

You can change the type of signal that FERRUPS responds to and how quickly FERRUPS responds. You can also

set up FERRUPS to restart automatically when the shutdown signal stops. See TIP 503 or call Best Power’s

Worldwide Service for more information.
