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 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 ex-
pected.
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.
CHECKING THE SITE WIRING FAULT (120V Models)
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 UPS is plugged into an
improperly wired AC wall outlet. If the UPS indicates a Site Wiring Fault (SWF), have a
Qualified Electrician correct the problem.
CONNECTING THE UPS TO AN AC SOURCE
Plug the UPS into a two pole, three wire, grounded AC wall outlet. The AC wall 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 PLUG THE
UPS INTO EXTENSION CORDS, ADAPTER PLUGS OR SURGE STRIPS. DO NOT
CUT THE INPUT PLUG OFF AND ATTEMPT TO HARDWIRE THIS UPS, DOING SO
WILL VOID THE WARRANTY.
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 connec-
tion.
CONNECTING YOUR EQUIPMENT
Plug the equipment into the output receptacles on the rear panel 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). DO NOT PLUG EXTENSION CORDS,
ADAPTER PLUGS OR SURGE STRIPS INTO THE OUTPUT RECEPTACLES OF THE
UPS.
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.
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 (Se-
rial or USB) to the appropriate communications port on the rear panel of the UPS. Con-
nect 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. (For USB port see Note on page 17).
RJ11 EPO (Emergency Power Off) PORT
(OPTIONAL)
Connect one end of the RJ11 cable to the EPO 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 EPO port is optional. The UPS works
properly without this connection. This connection is not for Telecommnication use.
Chapter 4: Operation
SYSTEM OVERVIEW
This double conversion On-Line UPS protects computers, servers, telecommuni-
cations, security and other electronic equipment from blackouts, brownouts, over-
voltages, and surges. This On-Line UPS converts the input AC to DC and then
back to a true sine wave AC output. The true sine wave output is regulated within
2% of the nominal output voltage. The Power Factor Correction (PFC) circuitry
corrects the input power factor to within 99% of unity and blocks the load generated
harmonic distortion from getting back on the input AC line. This On-Line UPS pro-
vides a continuous true sine wave output with zero transfer time and great regula-
tion to protect your mission critical equipment. The UPS will quietly and confidently
protect your system from power anomalies.
The UPS will charge the batteries when the UPS is 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 (55V (load dependent) - 150VAC). When a blackout, brownout, or an over-
voltage condition occurs while the UPS is in the On-Line mode or the Economy
mode; the UPS will transfer to the battery mode, the On-Battery indicator will illumi-
nate and the audible alarm will sound once every ten-seconds indicating that the
utility power is lost or unacceptable. When the utility power returns or is at an ac-
ceptable level, the UPS will automatically transfer back to the On-Line mode or the
Economy mode and start recharging the batteries. 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 equipment. When
the batteries reach the predetermined level the UPS will automatically shutdown
protecting the batteries from over discharging. Once the utility power returns the
UPS will automatically restart providing safe usable power to the connected equip-
ment and start recharging the batteries.
The Economy mode operation: The input utility power 'bypasses' the inverter cir-
cuit and is connected directly to the output of the UPS powering the connected
equipment while simultaneously charging the batteries. When a blackout, brown-
out, or an overvoltage condition occurs the UPS will transfer to the battery mode,
the inverter will turn on powering the connected equipment, the On-Battery indicator
will illuminate and the audible alarm will sound once every ten-seconds indicating
that the utility power is lost or unacceptable. When the utility power returns or is at
an acceptable level, the UPS will automatically transfer back to the Economy mode
and start recharging the batteries.
