The "Alarm Signal Contacts" are relay contacts (rated at 25 V AC/DC
and 250mA) that change state upon any alarm condition. Contacts that close
on an alarm or when the UPS is turned off are available between pins
23 and 24. Contacts that open on an alarm or when the UPS is turned off
are available between pins 24 and 25.
The "Inverter On Signal Contacts" are relay contacts (rated at 25 V AC/DC
and 250mA) that change state 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.
The "Remote Emergency Power Off" trigger is actuated by closing a circuit
between pins 6 and 21. This will force the UPS to SystemModeOff.
The "RS232 Communications Port" connections are found on Pin 7 (signal
ground), Pin 3 (receive data), and Pin 2 (transmit data). This port is
configured as DCE operating at 1200 baud (selectable 300, 1200, 4800, or
9600). Data is formated in 8 bit ASCII; 1 stop bit; full duplex; no parity.
This interface supports XON/XOFF. Hardware handshaking is not supported.
Refer to TIP501 for information regarding the FERRUPS User Interface
Command Language.
