2.7.3 Dual-Bus System

A dual-bus system consists of two independent UPS systems. Each UPS system
consists of one UPS or multiple UPSs connected in parallel. Of the two UPS
systems, one is the master system and the other is the slave system. The dual-bus
system is highly reliable and is suitable for loads with multiple input terminals.
You can install an optional static transfer switch (STS) to start a bus
synchronization controller (BSC) provided in standard configuration. The UPS
systems work in inverter mode or bypass mode.
