3.4.4 UPS Power connections
Figures 3.8 and 3.9 illustrate the UPS cabinet power terminal connections. The DPA-150 and DPA-250 cabinet diagrams
show the optional common battery links fitted so that the battery is connected to all the fitted power modules. If the
installation is to include separate batteries see paragraph 3.4.5 and figures 3.10 to 3.12 for cabling details.

Key Point:
In a redundant module system the overall system reliability is increased by using an individual
battery string for each UPS module as this extends the module redundancy to include the battery – i.e. if one
battery fails it only affects one UPS module.
