CHARGING THE BATTERY
CHECKING THE SITE WIRING FAULT (120V Models)
After plugging in the UPS, check the Site Wiring Fault (SWF) LED on the front
panel of the UPS. If the SWF LED is illuminated, the UPS is plugged into an
improperly wired AC outlet. If the UPS indicates a Site Wiring Fault (SWF),
have a Qualified Electrician correct the problem.
COMMUNICATIONS PORT CONNECTION (OPTIONAL)
The Power Monitoring Software and interface cables can be used with the UPS.
Use only the interface cables that come with these UPSs. Connect the inter-
face cable (Serial or USB) to the appropriate communications port on the rear
panel of the UPS. Connect the other end of the cable to the device that will be
monitoring/controlling the UPS. NOTE: Connecting to the Communications
Port is optional. The UPS works properly without this connection.
CONNECTING THE UPS TO AN AC SOURCE
Plug the UPS into a two pole, three wire, grounded receptacle only. Do not use
extension cords, adapter plugs, or surge strips.
NETWORK/PHONE/FAX/MODEM PROTECTION CONNECTION (OPTIONAL)
Connect a 10/100 Base-T network, single line phone, Fax or Modem line to the
RJ11/45 modular connectors on the rear panel of the UPS. This connection will
require another length of telephone or network cable. The cable coming from
the telephone service or networked system is connected to the port marked
“IN”. The equipment to be protected is connected to the port marked "OUT".
NOTE: Connecting to the Network/Phone/Fax/Modem modular connectors is
optional. The UPS works properly without this connection.
CONNECTING YOUR EQUIPMENT
Plug the equipment into the output receptacles on the rear panel of the UPS.
Do not use extension cords, adapter plugs or surge strips on the output of the
UPS. Ensure that you do not exceed the maximum output rating of the UPS
(refer to the information label or the Electrical Specifications in this manual).
CAUTION! DO NOT connect a laser printer to the output receptacles on the
UPS, unless the UPS is rated 2000VA or greater. A laser printer
draws significantly more power when printing than at idle and
may overload the UPS.
RJ11 REPO (Remote Emergency Power Off) PORT (OPTIONAL)
Connect one end of the RJ11 cable to the REPO port and the other end of the
RJ11 cable to the EPO switch. In the AC or the Battery mode short pin4 to pin5
for approximately 0.5-seconds to shutdown the UPS. The UPS must be turned
off and then back on again to restart the UPS. NOTE: Connecting to the
REPO port is optional. The UPS works properly without this connection.
The UPS will charge the internal batteries whenever the UPS is connected to
an AC source and there is an acceptable AC voltage present. It is recommended
that the UPS's batteries be charged for a minimum of 4 hours before use. The
UPS may be used immediately, however, the “On-Battery” runtime may be
less than normally expected. NOTE: If the UPS is going to be out of service or
stored for a prolonged period of time, the batteries must be recharged for at least
twenty-four hours every ninety days.

SYSTEM OVERVIEW
This Line-Interactive UPS protects computers, internetworking, and telecom-
munications equipment from blackouts, brownouts, overvoltages, and surges.
The AVR function continuously corrects the voltages, in-between the brownout
and overvoltage transfer points (80 - 164VAC/150 - 271VAC), to a safe usable
level. When the UPS is operating in the AVR mode the audible alarm will
remain silent and the Boost or the Buck indicator will blink. During normal AC
operation, the UPS will quietly and confidently protect your system from power
anomalies.
The UPS will charge the batteries with the UPS in the on or off position as long
as the UPS is plugged into the wall outlet and there is an acceptable AC voltage
present (80 - 164VAC/150 - 271VAC). When a blackout, brownout, or an
overvoltage condition occurs; the UPS will transfer to the battery mode, the On-
Battery indicator will illuminate and the audible alarm will sound once every ten-
seconds indicating that the commercial power is lost or unacceptable. When
the commercial power returns or is at an acceptable level, the UPS will auto-
matically transfer back to the AC normal mode and start recharging the batter-
ies. During an extended outage when there is approximately two-minutes of
backup time remaining the audible alarm will sound twice every five-seconds.
This Low Battery Warning is letting the user know that they should save all
open files and turn off their computer. When the batteries reach the predeter-
mined level the UPS will automatically shutdown protecting the batteries from
over discharging. Once the commercial power returns the UPS will automati-
cally restart, providing safe usable power to the connected equipment and start
recharging the batteries.

runs a five-second self test. Press and release the On/Off/Test Button after one
beep to turn the UPS off. The UPS will continue to charge the batteries when-
ever it is plugged into a wall outlet and there is acceptable AC voltage
present.
11

COMMUNICATIONS PORTS (RS232 and USB)
The RS232 communication port is a standard DB9 female with both RS232 and
simulated contact closure capability. The UPS will poll the port and activate
the port for RS232 or contact closure in accordance with the type of cable it
finds connected to the port. To change the port configuration requires the unit
be turned off and restarted with the desired cable connected. 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 to pin 9 for 4-
seconds. The shutdown command is only active in the battery mode)
Pin 4: Not Used
Pin 5: Ground
Pin 6: Not Used
Pin 7: Not Used
Pin 8: Simulated contact closure AC fail, NO
Pin 9: Atx Signal (high level: +12V +/-2V, low level: -15V +/- -2V)
DIPSWITCH SETTINGS
The dipswitch setting may be changed by the user to set the desired Inverter
(On-Battery) output voltage. The dipswitch must be set to the desired Inverter
(On-Battery) output voltage and then the UPS must be turned off and restarted
to reconfigure the microprocessor and save the changes. The Inverter (On-
Battery) output voltage setting can be either 120VAC (208VAC) default or 127VAC
(240VAC). Changing the Inverter (On-Battery) output voltage to 127VAC, will
also change the Buck setpoint. Changing the Inverter (On-Battery) output volt-
age to 240VAC, will also change the Brownout, Boost, Buck and Overvoltage
setpoints.
SELF TEST
The self test feature is useful to verify the correct operation of the UPS and the
condition of the batteries. With the UPS in the AC normal mode, press and
hold the On/Off/Test Button for four beeps, then release the button. The UPS
will perform a ten-second self test. During the self test, the UPS will switch to
battery power and the On-Battery LED will illuminate and the audible alarm will
sound. The length of the test that is automatically performed every two weeks
is longer than the start-up or user invoked test. This test will run for approxi-
mately fifteen-seconds to measure the battery’s capability to provide an ac-
ceptable amount of runtime. If the UPS fails a self test, one of the LEDs will
remain illuminated indicating the type of problem. NOTE: The UPS will auto-
matically perform a self test on start-up and every two weeks.
LOAD SHEDDING FUNCTION
The output receptacles are electrically wired into two segments to support the
"Load Shedding Function". The user can control the two segments individually
or both at the same time. The Load Shedding Function is controllable by the
Power Monitoring Software or the SNMP card.
12

WEAK/BAD BATTERY
The UPS automatically tests the battery’s condition and will illuminate the Weak/
Bad Battery LED and sound the alarm. This alarm will be repeated until the
batteries pass a self test. If the battery is weak, bad or disconnected, the
Weak/Bad Battery LED will illuminate and the alarm will beep three times every
five-minutes until the battery is reconnected or replaced. It is recommended
that the UPS be allowed to charge overnight before performing a battery test to
confirm a Weak/Bad Battery condition.
NOTE: If the UPS has a Weak/Bad Battery Alarm after reconnecting or replac-
ing the batteries, the user must initiate a self test to clear the Weak/Bad Bat-
tery Alarm. To initiate a self test see section 4 "SELF TEST".
OVERLOAD
When the amount of load attached to the UPS exceeds its power rating, the
Overload LED will illuminate (AC mode only) and the UPS will sound a constant
alarm (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. If the UPS
shuts down because of an Overload condition in the battery mode, the UPS
must perform an Inverter function or a Self Test to clear the Overload Alarm.
POWER MONITORING SOFTWARE
The UPS comes with a Power Monitoring Software CD. See the software CD
for the installation of the Power Monitoring Software.
USB PORT
The USB protocol is HID. The HID USB driver is standard in the Windows OS.
Simply plug the USB cable into the UPS and the computer then follow the
prompts on the screen.
OPTION SLOT
The option slot on the rear panel of the UPS is for option cards. Contact your
local dealer for the available option cards.
ALARMS
ON BATTERY
When the UPS is operating on the batteries, the On-Battery LED will illuminate
and the audible alarm will sound once every ten-seconds. The alarm will stop
once the UPS returns to the AC normal mode.
LOW BATTERY WARNING
The UPS will sound two beeps every five-seconds when the battery reserve
runs low. This condition will continue until AC returns or the UPS shuts down
from battery exhaustion.
UPS FAULT
When the UPS detects a hardware fault, the Fault LED will illuminate and the
UPS will sound a constant alarm. The fault condition, in some instances, may
be reset by turning the UPS off and then on.
RJ11 REPO (Remote Emergency Power Off) PORT
Connect one end of the RJ11 cable to the REPO port and the other end of the
RJ11 cable to the EPO switch. In the AC or the Battery mode short pin4 to pin5
for approximately 0.5-seconds to shutdown the UPS. The UPS must be turned
off and then back on again to restart the UPS.
