Installing in a parallel configuration
WARNING:
This equipment must be installed by a licensed electrician or trained service
personnel familiar with high-power circuitry
A UPS connected to a Bus Bar with a paralleling line cord is identified as a member of the parallel system.
The Bus Bar connects the line and load to a common power bus. A parallel system can be configured for
capacity or redundancy.
The UPS models in a parallel configuration require a dedicated branch circuit that meets the following
requirements:
Circuit with overcurrent protection, depending on parallel configuration:
Number of UPSs in parallel
