BATTERY TEST SWITCH - This is a momentary, push button switch. Battery condition is vital to
the UPS performance, particularly during a power outage. During normal operation with inverter ON, load
applied to the unit and the Battery Bar Graph showing the battery at a full charge, this function switch
may be used. By pressing this switch in for at least two seconds, a battery acceptance diagnostic will be
run by the internal microprocessor. During the battery test, the Replace L.E.D. will flash and the On Batt
L.E.D. will be it. The test will run for approx. 30 seconds.
REPLACE BATTERY LED – After the battery acceptance diagnostic test has discovered that the
batteries are excessively fatigued, the amber L.E.D. above this switch will light advising the user that the
Batteries are bad and should be replaced or battery module is not connected to the UPS.
ALARM RESET SWITCH - This is a momentary, push button switch. During a system FAULT or
power failure, an audible alarm will be present. Once this switch is pressed in for at least two seconds,
the audible alarm will be silenced. The L.E.D. above the switch will remain unchanged. Additional Alarm
conditions will re-annunciate the alarm, which then can be silenced again.
FAULT LED - If a FAULT condition occurs, this red L.E.D. will illuminate.
UPS REAR PANEL
INTERFACE - One CPC Type, 37 position reversed sex connectors provided for critical loads.
Continuous power is provided here and is monitored by the LOAD L.E.D.s as long as the INVERTER is
functioning. The Loads ON/OFF Switch must be enabled for power to be present here. 120VAC Fan
Power, Fan sensor and Temp sensors are also provided.
RS232 CONNECTOR - DB-9 subminiature female connectors provided for intelligent computer
monitoring systems. See SIGNALS AND INTERFACING Section for specific pin-outs.
CONTROL PANEL CONNECTOR - DB-25 subminiature female connectors provided for
interfacing the control panel. See SIGNALS AND INTERFACING Section for specific pin-outs.
INPUT – One CPC Type, 3 position inlet connector for AC input.
GROUND - A 10-32 x 3/4 threaded stud for system rack grounding.
SNMP INTERFACE - (OPTIONAL) An add-on card that provides Simple Network Management
Protocol (SNMP) access to the UPS controller via a RJ45 connector (LAN). The second RJ45 connector
(RS232) provides a second RS232 port to the controller.
