Installation and User Manual

1.8Parallel Connected UPS Units

For installations with redundant units, take into account only the units required to supply the load power (e.g. for an installation made up of 3 parallel-connected UPS units, one being redundant, only 2 UPS units are used to determine bypass AC source and load currents and cable cross-sections).

Table 1-5 serves as an example for a parallel connected installation comprising up to four UPS units.
