Event Descriptions, continued
Blackout - A blackout is a complete loss of AC Line power. * *
Frequency High - A frequency high is a power line problem where the input
frequency increases. * *
Frequency Low - A frequency low is a power line problem where the input
frequency decreases. * *
Output Voltage Low - This is a warning that the output of the UPS is too
heavily loaded. Reduce the load connected to the UPS.
Output Voltage High - This can be caused by the unit being out of calibra-
tion, or the unit is detecting an internal fault causing the overvoltage condition.
Have the unit serviced by an authorized Alpha Repair Depot.
Output Power Overload - This is a condition where the output of the UPS is
too heavily loaded. If this is not corrected, the unit may go into a shutdown
condition to protect the UPS's internal circuitry.
Output VA Overload - This condition is also caused by the UPS being
overloaded on the output. Reduce the load on the output of the UPS.
Output Voltage Shutdown - The UPS was overloaded and, to protect the
internal circuitry, terminated the output to the load. Before restarting the UPS,
remove nonessential equipment from the output and reduce the load.
Output Short Circuit - A load was connected to the UPS that was shorted.
This could be caused by a miswired AC power cord or equipment connected
to the UPS that is in need of repair. Note: This condition activates the
SERVICE alarm, along with an audible alarm which can be cleared by
pressing the MUTE key.
Internal Temperature High - The internal temperature of the UPS, measured
by internal circuitry, was found to be too high. This could be caused by a
sustained overload on the output of the UPS, a blocked fan (if equipped), or
operating the unit in an excessively high ambient temperature. To prolong the
life of the batteries and UPS components, determine and correct the cause of
the overtemperature condition.
Input Line Fail - The UPS switched to backup power to protect the equip-
ment for one (or more) of the above conditions. * *
Normal Line Mode - Indicates that the UPS is operating on, or has switched
back to, normal AC Line power.
Test Mode - Indicates the UPS was put into a test mode condition either by
the TEST SCHEDULE routine or by pressing the TEST button on the
Intelligent Interface Device's panel. The unit will switch to backup power while
in the test mode. * *

* * Indicates events that cause the UPS to operate in "LINE FAILURE" mode.
UPS Startup
1. Plug the UPS power cord into a wall receptacle. If the UPS is hardwired,
switch the AC circuit breaker ON. The "LINE PRESENT" indicator will
come ON to indicate that the UPS is running on AC Line power. The
other front panel indicators should be OFF.
2. Switch the rear panel "BATTERY" circuit breaker(s) ON to activate the
DC circuit.
3. Test the unit for proper operation (see "UPS Test" below).
WHEN AC LINE POWER IS NOT AVAILABLE:
1. Plug the UPS power cord into a wall receptacle, or switch the AC circuit
breaker ON. The "LINE PRESENT" indicator will remain OFF.
2. Switch the rear panel "BATTERY" circuit breaker(s) ON to activate the
DC circuit.
3. Press the TEST key located on the front panel keypad. The switch will
start the UPS from battery power. Since many computer and telephone
systems require two to three times their maximum input amperage during
start-up, it may be necessary to reduce the load in order to start the UPS.
Run time is limited to the condition of the batteries and UPS loading.
Note: When the UPS first starts, it will emit a continuous tone to indicate a
cold start. To defeat the tone, press the MUTE switch.
UPS Test
1. Test the UPS by unplugging the AC power cord from the wall receptacle,
or by switching OFF the AC circuit breaker (hardwired units). The
front panel amber "LINE FAILURE" LED will light as the UPS initiates
LINE FAILURE operation.
2. Plug the AC power cord back into the wall receptacle, or switch the AC
circuit breaker ON. The "LINE PRESENT" LED will come ON to indicate
the presence of AC Line power. Within 20 seconds the "LINE FAILURE"
LED will shut OFF to indicate that the UPS has resumed LINE PRESENT
operation.
3. Once the UPS has been tested, connect the load to the rear panel output
receptacles. Note: The load should be switched OFF prior to connection.
Note: The UPS can also be tested by pressing the TEST key on the Intelligent
Interface Device. To end the 1-minute self-test, press the TEST key again.
Set Time and Date
1. Access the USER PARAMETER menu and enter the security code.
2. Select the SET TIME screen and set the (HH-MM-SS) fields using the #
keys on the keypad or the up or down arrows to advance or decrement
the entries. Press the ENTER key to exit the screen.
3. Select the SET DATE screen and set the (MM-DD-YY) fields using the #
keys on the keypad or the up or down arrows to advance or decrement
the entries. Press the ENTER key to exit the screen.
