8.4 LBS System
8.4.1 Cabinet Installation
LBS system consists of two independent UPS systems, each containing one or more parallel UPS modules, as shown in
Figure 8.5 below and Figure 8.6 on the next page. The LBS system has high reliability and is applicable to the load with
multiple inputs. For single-input load, an STS can be installed to feed power to the load.
The system uses the LBS cables to keep the output of two independent UPS systems in synchronization. One set of UPS
system (single/parallel) is designated as the master, the other set of UPS system (single/parallel) is designated as the slave
for the operation in LBS mode.
