USB COMMUNICATIONS PORT
This UPS supports USB communications. The USB communications protocol is HID.
The HID USB driver comes standard in the Windows OS. Simply plug the USB cable
into the UPS and the computer then follow the prompts on the screen.
SNMP CARD
The
included SNMP Card is web based and is used for monitoring and control-
ling the UPS. See the SNMP Card's Manual for configuring and setting up the
SNMP Card.
LED Function
The UPS provides both visual and audible indicators. There are three visual indicators:
an AC mode Green LED, a Battery mode Yellow LED and a Fault condition Red LED.
ALARMS
ON BATTERY
When the UPS is operating on the batteries, the AC mode LED will extinguish, the Bat-
tery mode LED will illuminate and the alarm will sound one beep every five seconds.
Once the UPS returns to the normal AC mode, the alarm will stop, the Battery mode LED
will extinguish and the AC mode LED will illuminate.
WEAK/BAD BATTERY
The UPS automatically tests the battery’s condition. If the battery is weak, bad or
disconnected, the Fault LED will flash and the alarm will sound three beeps every five
minutes until the battery is either reconnected or replaced. This alarm will be repeated
until the batteries pass a self-test. It is recommended that the UPS be allowed to charge
overnight before performing a battery test to confirm a Weak/Bad Battery condition.
OVERLOAD
When the amount of load attached to the UPS exceeds its power rating, the Fault LED
will illuminate and the alarm will sound continuously (AC and Battery modes). This
alarm will remain on until the excess load is removed or the UPS’s self protection circuit
shuts the UPS down. To clear the overload alarm when the UPS has shutdown requires
that the UPS perform a battery test. First remove part of the load, then turn the UPS on,
the Fault LED and the alarm will be on. Second either use the Test Button or unplug the
input power cord to perform the battery test.
LOW BATTERY WARNING
When the batteries reach the predetermined level, the alarm will sound two beeps
every five seconds and the Battery mode LED will flash. This condition will continue until
either AC returns or the UPS’s self protection circuit shuts the UPS down to protect the
battery from over discharging.
UPS FAULT
When the UPS detects an internal fault, the Fault LED will illuminate, the alarm will
sound continuously and the output will be turned off. The fault condition, in some in-
stances, may be reset by turning the UPS off and then on. If the fault condition does not
clear the UPS must be sent in for service.
BATTERY OVER CHARGE PROTECTION
If the charger is providing too much voltage to the battery the UPS will turn off the
charger to protect the battery. When the charger voltage exceeds 45V the charger will
turn off. The alarm will sound three beeps every five seconds and the Fault LED will
flash and the alarm will sound three beeps every 5-seconds. The UPS will automatically
transfer to the battery mode and operate until the UPS shuts down due to battery ex-
haustion. In some instances, the charger may be reset by turning the UPS off and then
on. If the charger does not rest then the UPS must be sent in for service.
RS232 COMMUNICATIONS PORT
The power monitoring software and interface cables can be used with the UPS. The
RS232 communication port is a standard DB9 female with both RS232 and simulated
contact closure capability. The pinout for the port is depicted per the chart below:
Pin 1: Simulated contact closure Low Battery Warning, NO
Pin 2: /TXD
Pin 3: /RXD and receive UPS shutdown command (connect a minimum of +5VDC
to a maximum of +12VDC for 4-seconds to completely shutdown the
UPS. The shutdown command is ONLY active in the battery mode)
Pin 5: Ground
Pin 8: Simulated contact closure AC fail, NO
Pins 4, 6, 7, 9: Not Used

TEST BUTTON
To perform a ten-second user invoked battery test: With the UPS in the AC normal
mode, press and hold the On/Off/Test Button until the alarm sounds four beeps, and
then release. During the test, the UPS will switch to the Battery mode, the Battery mode
LED will illuminate and the alarm will sound.
