SYSTEM OVERVIEW
This Line-Interactive UPS protects computers, internetworking, and telecom-
municationsequipmentfromblackouts, brownouts, overvoltages, and surges.
TheAVR function continuously corrects the voltages,in-betweenthebrownout
and overvoltage transfer points (80 - 164VAC), to a safe usable level. When
the UPS is operating in theAVR mode the audible alarm will remain silent and
theACNormaliconwillflash. DuringnormalACoperation,theUPSwillquietly
and confidently protect your system from power anomalies.
CHARGING THE BATTERY
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 recom-
mended 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 re-
charged for at least twenty-four hours every ninety days.
CHECKING THE SITE WIRING FAULT
After plugging the UPS into the AC wall outlet, check the Site Wiring Fault
(SWF) icon on the front panel of the UPS. If the SWF icon is illuminated, the
UPSis plugged into an improperly wiredAC wall outlet. Ifthe 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
interface 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 Communi-
cations Port is optional. The UPS works properly without this connection.
(For USB port see Note on page 17).
CONNECTING THE UPS TO AN AC SOURCE
PlugtheUPSintoatwo pole, three wire, groundedAC wall outlet. TheACwall
outlet shall be near the UPS and shall be easily accessible. The plug on the
input power cord on this UPS series is intended to serve as a disconnect
device. Do not use extension cords, adapter plugs, or surge strips.
NETWORK/PHONE/FAX/MODEM PROTECTION CONNECTION (OP-
TIONAL)
Connecta10/100Base-Tnetwork,singlelinephone,FaxorModemlinetothe
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
fromthetelephoneservice or networkedsystemisconnectedtothe portmarked
“IN”. The equipment to be protected is connected to the port marked "OUT".
NOTE: ConnectingtotheNetwork/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.
This connection is not for Telecommunication use.

TheUPSwill charge the batteries with the UPS intheon or off position as long
astheUPSispluggedintothewalloutletandthere is an acceptableAC voltage
present (80 - 164VAC). When a blackout, brownout, or an overvoltage condi-
tion occurs; the UPS will transfer to the battery mode, the On-Battery icon will
illuminateand the audible alarmwill sound once everyten-seconds indicating
that the commercial power is lost or unacceptable. When the commercial
power returns or is at an acceptable level, the UPS will automatically transfer
back to the AC normal mode and start recharging the batteries. During an
extended outage when there is approximately two-minutes of backup time re-
maining the audible alarm will sound twice every five-seconds. This Low Bat-
tery Warning is letting the user know that they should save all open files and
turn off their computer. When the batteries reach the predetermined level the
UPS will automatically shutdown protecting the batteries from over discharg-
ing. Once the commercial power returns the UPS will automatically restart,
providingsafe usable power to the connected equipmentand start recharging
thebatteries.
