BATTERY TEST SWITCH
- This is a momentary, two position 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.
REPLACE BATTERY LED
– After the battery acceptance diagnostic test has discovered that the
batteries are excessively fatigued, the red 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. During battery
test this LED will flash red for approx. 30 seconds.
ALARM RESET SWITCH
- This is a momentary, two position 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.
FAULT LED
- If a FAULT condition occurs, this red L.E.D. will illuminate.
BATTLE SHORT SWITCH
– Activating this switch (pull out and up) will disable the UPS over
temperature sensors.
BATTLE SHORT LED
– A red L.E.D. will illuminate indicating the UPS has been set to ignore over
temperature conditions.

OUTPUTS
- Two 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.
RS232 CONNECTOR
- DB-25 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.
DC INPUT
- An interface connector provided for external battery connections. Additional batteries may
be added to increase load run times during a utility power failure.
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.
TEMPERATURE SENSOR
– A DB-9 female connector provided for external temperature sensor
inputs from the rack.
EXTERNAL FAN CONNECTOR
– A CPC Type, 7 position connector provided for external fan
power and fan alarm input from the rack.
