Chapter 6   Configuration Program 
The final step of installation may require custom configuration of your UPS using the enclosed configuration program. 
Some configuration settings may be changed only while the UPS is off. These should be set before the UPS is put 
into full-time service powering the critical load.   
For most users operating with 230VAC and with no external batteries, the factory default settings will be adequate. 
6.1   Configuration Program Features 
 Select L-N output voltages to match local voltages. 
 Enable/Disable Auto-Restart. 
 Select frequency converter operation with a fixed output frequency of 50 or 60 Hz. 
 Set the Low Battery Warning alarm time from 2 to 30 minutes. 
 Enable/Disable the Auto-Battery test. 
 Set the Auto-Battery test to 8, 12, 16, 20 or 26 weeks. 
 Specify the number of external battery cabinets connected to the UPS to adjust the remaining run time
