Figure 74: Setup, Battery End of backup voltage limit
This function enables you to define the battery voltage at which the UPS will cease to provide
backup power and will shut itself down. This helps avoid overly deep battery discharge, which
shortens battery life.
The voltage limit is expressed in terms of volts per battery block. The normal voltage of a battery
block is between 12 and 13.5 volts. The end-of-backup battery voltage limit can be from 10 to 11
volts per battery block. The UPS computes the average voltage per battery block, based on 40
cells.

Setup > Battery > BATTERY CAPACITY IN Ah
Use this function to tell the UPS the total capacity (in ampere/hours) of the connected battery
strings.
