§ Battery temperature
§ Additional indications shall provide maintenance assistance
Display of Operating Curves: The graphical display shall be capable of displaying curves and bar
graphs of the above-mentioned measured values for significant periods.
Time-Stamped Historical Events: This function shall time-stamp and store all important status
changes, anomaliesand faults, and make this information available for automatic or user-requested
consultation.
B. LED Status Indicators: The UPS control panel shall provide three LEDs that signal the following

audible alarm.
E. Emergency Power Off (EPO): The UPS shall be equipped with a local emergency power off button
and dry contact input that can be used to command UPS shut down remotely. Activation of this
command shall lead to the following actions:
§ inverter shutdown
§ opening of the static bypass switch and the battery circuit breaker
§ opening of input and output devices
§ opening of an isolated dry contact on the programmable relay board
F. DB-9 Connector: One DB-9 connector with serial output will be provided for field diagnostics.
G. Dry Contacts: The UPS shall be provided standard with a programmable input/output relay board.
This board shall have 8 dry contacts, i.e., 6 for input signals and 2 for output signals.Contacts shall be
programmed as:
§ UPS on Line

§ UPS on Battery
§ UPS Battery Low
§ General alarm
§ Remote UPS on (input)
§ Remote UPS off (input)
The contacts will be normally open and will change state to indicate the operating status. The contacts
will be rated at 2.0 A (250 VDC / 30 VDC).
