PHONE/FAX/NETWORK PROTECTION CONNECTION
(OPTIONAL)
Connect a 10/100 Base-T network, single line phone, or fax 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 tele-
phone 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 Phone/Fax/Network modular connectors is optional. The
UPS works properly without this connection.
SYSTEM OVERVIEW
This Line-Interactive UPS protects computers, servers, telecom systems, VoIP sys-
tems, security systems, and a variety of electronic equipment from blackouts, brown-
outs, overvoltages, and surges. The AVR function continuously corrects the volt-
ages, in-between the brownout and overvoltage transfer points (90 - 150VAC), to a
safe usable level. When the UPS is operating in the AVR mode the audible alarm
will remain silent and the AC normal mode 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 when the
UPS is plugged into the wall outlet and there is an acceptable AC voltage present
(90 - 150VAC). 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 five 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 ap-
proximately two minutes of backup time remaining the audible alarm will sound
twice every five seconds. This Low Battery Warning is informing the user 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 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.
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 (90 - 150VAC). 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. Typical battery life is 3 to 5
years. Environmental factors do affect battery life. High temperatures, poor
utility power, and frequent, short duration discharges have a negative impact on
battery life.
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.
USB COMMUNICATIONS PORT CONNECTION
(OPTIONAL)
This UPS series supports USB communications. The power monitoring soft-
ware and interface cable can be used with the UPS. Use only the interface
cable that come with these UPSs. The USB communications protocol is HID.
The HID USB driver comes standard in the Windows OS. Simply connect the
USB cable to the USB communications port on the rear panel of the UPS.
Connect the other end of the USB cable to the device that will be monitoring/
controlling the UPS and then follow the prompts on the screen.
NOTE:
When
using the UPS's USB port with Windows XP, 7 or 8 the Power Options in the
Control Panel may need to be configured.
Connecting to the Communications
Port is optional. The UPS works properly without this connection.
CHECKING THE SITE WIRING FAULT
After plugging the UPS into the wall outlet, check the LCD screen on the front
panel of the UPS for a Site Wiring Fault (S.L.F). If the S.L.F is illuminated, the
UPS is plugged into an improperly wired wall outlet. If the UPS indicates a Site
Wiring Fault (S.L.F), have a Qualified Electrician correct the problem.
CAUTION!
The TNV connector shall use the same type of RJ45.
POWER MONITORING SOFTWARE
This UPS supports Minuteman's SentryHD power monitoring software. Please
go to our web site at www.minutemanups.com/support, then look under Down-
loads, and then Software Download Center. Please download (Free of Charge)
the latest version of the Minuteman SentryHD software.
TURNING THE UPS ON / OFF
To turn the UPS on: press and hold the On/Off/Test Button until the alarm sounds
one beep and then release. The UPS will perform a five second battery test. Once
the UPS has passed the battery test the UPS will reset to the norml AC mode and
provide power to the connected load. To turn the UPS off: press and hold the On/
Off/Test Button until the alarm sounds one beep and then release.
TEST BUTTON
To perform a ten-second user invoked battery test: With the UPS in the normal AC
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 On-
Battery icon will illuminate and the alarm will sound.
