Accessing the configuration program via USB is a new feature of the S4K2U-5C. For most users, the factory default

settings.
The USB configuration program allows these features of the S4K2U-5C to be changed:
•
Enable/Disable Auto-Restart
•
Select frequency converter operation with a fixed output frequency of 50 Hz or 60 Hz, bypass disabled
•

•
Enable/Disable the Auto-Battery test
•
Enable/Disable Auto-Restart after removing Remote Shutdown
•
Set the wiring mode of Remote Shutdown

Set the Auto-Battery test to 7, 14, 21, or 28 days
•
Select the number of external battery cabinets connected to the UPS to adjust the remaining run time calculated by

WARNING
The output voltage settings cannot be changed while the UPS is on and powering connected loads.
NOTES:
•
Programming the output voltage of a 230 V model to 220 V automatically derates the UPS to 96% of both the VA
and Watt ratings. Refer to “9.0 Specifications” for VA and Watt ratings.
•
The configuration program is compatible with UPS models S4K2UXXXX-5C, as in S4K2U3000-5C. It is not compatible
with earlier versions of the S4K2U-5 UPS.
•
A computer running Windows 2000®, XP® or Vista® is required to set up and run the configuration program.
