Abstract
A multiple UPS system has a plurality of UPS subsystems with a separate UPS data communications bus coupling a controller of each UPS subsystem to an associated controller of an associated tie cabinet. The multiple UPS system further includes a data communications tie bus that couples the controllers of the tie cabinets to each other. The controllers of the tie cabinets arbitrate power line based coordinating signals between the UPS buses without the use of auxiliary signals.
