Figure 6 Battery Cabinet Grounding Configuration
Large, open-rack battery systems are normally either locally grounded or left ungrounded, depend-
ing on local code requirements.
Battery cabinet systems, on the other hand, should be grounded to the UPS module ground bus.
The figure above illustrates how a simple one-cabinet system would be grounded. For systems with
multiple cabinets, the same configuration would apply. However, for simplicity the installer can
connect all the battery cabinet grounds for a particular module together and run a single ground
conductor to that UPS module ground.
