5.8 Manual Bypass Mode
The UPS can be 'forced' into manual bypass by simultaneously pressing the ON and OFF buttons for
3 seconds. The UPS will then be in bypass mode and the load will be connected directly to the source.
The Bypass icon on the LCD display will be illuminated. This feature is used when an external main-
tenance bypass switch is installed and the UPS needs to be removed and/or serviced.
6. Alarms
6.1 “BACKUP” (slow alarm)
When in back-up mode, the UPS sounds an audible alarm. The alarm stops when the UPS returns to
LINE NORMAL operation. The alarm can be silenced by briefly pressing the “ON/TEST” button when
the ON BATTERY alarm sounds.
6.2 “LOW BATTERY” (rapid alarm)
In back-up mode, when the battery level runs low, the UPS beeps rapidly until either the UPS shuts
down due to battery depletion or it returns to LINE NORMAL operation.
NOTE: The alarm can not be silenced under this condition.
6.3 “OVERLOAD” (continuous alarm)
When the UPS is overloaded (i.e., the connected load(s) exceed the maximum rated capacity) the
UPS emits a continuous tone to warn of an overload condition, and displays the fault code “E04.”
Disconnect non-critical loads from the UPS to eliminate the overload.
6.4 “REPLACE BATTERY” (continuous alarm)
The UPS emits a continuous tone if the battery fails the self-test. See section 10 for instruction on
user battery replacement or contact tech support for assistance.
7. Software Options
7.1 Power Monitoring Software
NOTE: Please refer to the back of the software CD's holder for installation instructions. For operational
instrucions, install the software, launch the program then click HELP in the upper left corner of the
software application screen. Alternately, please visit our website to download the software User Manual.
The software is applied via the standard RS-232 interface to perform monitoring functions, as well as
as well as to implement an orderly shutdown of a computer in the event of a continuous power failure
In addition, the software displays diagnostic features, such as: input and output voltage, input and output
frequency, battery and load level, visually on your computer monitor.
The software is usable with Windows 95 or higher, Windows NT V3.5 or later, and others. Contact tech
support for more information on alternative computer OS compatible software.
7.2 Interface Kits
Included interface kit provides UPS monitoring. Each kit includes a special cable to convert status signals
from the UPS into signals which individual operating systems recognize. One end of the cable is connec-
ted to the remote port on the UPS and the other end to either the COM 1 or COM 2 port on the computer.
NOTE: Use only a factory supplied or authorized monitoring cable.

5.9 Shutdown Mode
In this mode, the UPS ceases supplying power to the load after battery depletion while waiting for the
return of utility power. If utility power is not restored, an external device, such as a server with software
connected to the UPS via the RS-232 interface, can command the UPS to shutdown. This is typically
done to preserve battery capacity after the proper shutdown of protected loads.
