Configuring Load Segments

Considerations

Before connecting the UPS to other devices, verify the load the UPS will be carrying. Make sure that the cumulative total device Watts or VA rating (the load) does not exceed the Watts or VA rating for the UPS.

When the UPS batteries are fully charged, backup time for R6000 Series units at recommended 80% load is greater than 8 minutes without Extended Runtime Modules attached. Battery runtimes can surpass 15 minutes and more with partial loads, while ERM additions can increase runtimes up to 30 minutes, even at 80% loads. Keep this in mind when loading the UPS.

Battery runtimes may vary depending on several factors, including, but not limited to: ambient temperature; age of batteries; and, number of cycles.

Table 2-2

Load Effect on Backup Time

Load %	Estimated Backup Time
100	Greater than 6 minutes
80	Greater than 8 minutes
50	Greater than 15 minutes
80% plus 1 ERM	Greater than 18 minutes
80% plus 2 ERMs	Up to 30 minutes

NOTE: Compaq recommends the load should not exceed 80% of the Compaq

R6000 UPS rated output.

Attaching the Load Segments

Attach the load equipment to the appropriate UPS output receptacles using approved power cords. See “Load Segments” in this section for receptacle configuration.
