Battery Cabinets
Run times in this table are approximate. They are based on new, fully charged standard battery modules at a temperature of 77°F (25°C)
with 100% resistive UPS loading. Run times listed above can vary by ±5% due to manufacturing variances of the individual batteries.
Using the configuration program, the user may specify the number of external battery cabinets
attached to the UPS. The factory default is programmed for internal batteries only.
Table 21 shows the estimated run times at different loads.
