NOTE:  For high voltage UPSs, the  Site Wiring Fault function is disabled by default, but can 
be manually enabled.  
  
To change the UPS configuration parameters:  
1. Place the UPS in Configure mode  (on page 39 ).  
The LEDs associated with the currently configured parameters illuminate. A flashing cursor indicates 
where you are in the configuration process as you scroll through the available settings.  
2. Press the On button to scroll through the options. Each time the On button is pressed, the audible 
alarm sounds.  
3. If the On b utton is pressed and the UPS does not respond, the UPS is in Operate mode  (on page 
38 ). Start over with step 1.  
4. Press the Off button once to toggle the selected option on or off.   
5. Repeat steps 2 and 3 for each option.  
6. To save the con figuration settings and exit Configure mode, press and hold the Test/Alarm Reset 
button for 3 seconds.  
  
 
NOTE:  Configure mode times out after 2 minutes of inactivity. If the Test/Alarm Reset button 
has not been pressed, any new selections are not saved.  
  
For the location of buttons, see "UPS front panel controls  (on page 8 )." 
For the location of LEDs, see " UPS front panel LED indicators  (on page 8 )." 
 
In itiating a self -test 
To initiate a self -test, press and hold the Test/Alarm Reset button  (" UPS front panel controls " on page 8) 
for three seconds.  
If the UPS detects a problem, the appropriate LED  (" UPS front panel LED indicators " on page 8) 
illuminates and an audible alarm may sound.

For information on what to do if the self -test detects a problem, see " Troubleshooting (on page 52 )."  
Silencing an audible alarm 
To silence an alarm, press the Test/Alarm Reset button  (" UPS front panel controls " on page 8).   
  IMPO
RTANT:    
•   Although the audible alarm silences, the condition that caused the alarm to sound may still 
exist.  
•   If a utility power failure caused the alarm, the alarm silences after power is restored.  
  
For information about audible alarm conditions, see "LED  and audible alarm troubleshooting  (" LED 
troubleshooting " on page 52)." 
 
Verifying the REPO port connection    
 
NOTE:  While testing, operate connected equipment in a safe  test mode so the effects do not 
disrupt critical operations.  
  
After  connecting the REPO port  (on page 21 ): 
1.  Initiate a REPO by closing the REPO contact.  
The Self Test, Battery Fault, Site Wiring Fault, Overtemperature, Overload, and  Utility LEDs flash. 
  
  CAUTION:
  If the polarity is reversed while connecting the REPO port, the UPS powers up 
normally.  
  
2.  Verify proper connection of the REPO port:  
a. Power up the UPS  (" Starting power to the load" on page 26 ). 
b.  Disconnect the REPO port.  
c. Reconnect the REPO port.  
If the polarity is correct, the REPO connectors can be disconnected, and then reconnected, 
without initiating a REPO.  
d. Verify  that the UPS remains in Operate mode  (on page  38).  
e. If a REPO is initiated, the polarity is reversed. Check and correct the connections.   
Powering down the UPS 
1. Shut down all load devices.  
2. Press the Off button to take the UPS out of Operate mode. Power to the load receptacles ceases.  
The On Battery LED and Load Level indicator flash.  
3. Disconnect the UPS from utility power.  
4. Wait at least 60 seconds for the UPS internal circuitry to discharge.

Important battery safety information    
  WARNING:
  The unit contains sealed lead -acid battery modules. To prevent fire or chemical 
burns:  
•   Do not attempt to recharge batteries after removal from the unit.  
•   Do not disassemble, crush, or puncture the batteries.  
•   Do not short the external contacts of the batteries.  
•   Do not immerse the batteries in water.  
•   Do not expose to temperatures higher than 60°C (140°F).  
  
 
    
						

							
 
Maintenance  45  
  WARNING:
  To prevent personal injury from hazardous energy:  
•   Remove watches, rings, or other metal objects.  
•   Use tools with insulated handles.  
•   Do not place tools or metal  parts on top of batteries.  
  
 
   
  WARNING:
  To prevent personal injury, prepare the area and observe all materials -handling 
procedures when transporting a battery module. Battery modules weigh 20  kg (44.1 lb).  
  
 
   
  NOTE:  Replace all battery modules at the same time.  
  
 
B attery care and storage guidelines 
• Minimize the amount of time the UPS uses battery power by matching the UPS configur ation with the 
utility voltage. Refer to "Configuring the UPS  (on page 40 )."  
• Keep the area around the UPS clean and dust- free. If the environment is very dusty, clean the outside 
of the UPS regularly with a vacuum cleaner.  
• Maintain the ambient temperature at 25°C (77°F).  
• If storing a UPS for an extended period, recharge the batteries every 6 months:    
  CAUTION:
  Because of the short shelf life of the batteries, avoid storing a battery spare as a 
backup. Do not maintain an inventory of spare batteries on site unless a procedure to keep 
these batteries charged while in storage is implemented.  
  
a.  Connect the UPS to utility power.  
b. Allow the UPS to remain in Standby mode.  
c. Allow the  UPS to charge the batteries for at least 24 hours.  
d. Update the battery recharge date label.   
Determining when to replace batteries  
When the Battery Fault LED illuminates, batteries might need to be replaced within 30 to 60 days.  
When a battery alarm sounds, initiate a UPS battery self -test to verify that battery replacement is required. 
If the Battery Fault LED remains illuminated, replace the batteries as soon as possible.  
For more information on initiating a self -test, see " Initiating a self -test  (on page 41 )." 
For the location of LEDs, see " UPS front panel LED indicators  (on page 8 )." 
 
Obtaining new batteries  
New batteries might be required within 30 to 60 days when the Battery Fault LED illuminates red. Obtain 
spare batteries for the UPS when this occurs.  
Spare battery modules are available for this UPS. The UPS spare battery kit part number is 517703 -001.  
   
						

							
 
Maintenance  46  
  CAUTION:
  Because of the short shelf life of the batteries, avoid storing a battery spare as a 
backup. Do not maintain an inventory of spare batteries on site unless a procedure to keep 
these batteries charged while  in storage is implemented. 
  
 
U PS battery replacement procedure   
  WARNING:

Maintenance  47  
  
 
To replace the components, reverse the removal procedure.  
  
  IMPORTANT:
  Charge the batteries for at least 24 hours before supplying backup power to 
de vices. The batteries charge to:  
•   80 percent of their capacity within 3 hours  
•   100 percent of their capacity within 48 hours  
  
 
T esting the new battery module  
After installing the new battery module, press the  Test/Alarm Reset button to initiate a self -test  (" Initiating a 
self -test " on page 41 ). 
  
  IMPORTANT:
  The UPS does not execute a self -test until the batteries are 90 percent charged.  
  
   
  IMPORTANT:
  Charge the batteries for at least 24 hours before supplying backup power to 
devices. The batteries charge to:
