2.4.2.2 ECM

The control module consists of two energy control modules (ECMs) in active/standby mode.
Each ECM provides one bus synchronization controller (BSC) port and one PARALLEL port,
as shown in
Figure 2-10 ECM
In a parallel system, the PARALLEL ports on ECMs are interconnected in the shape of a ring
using parallel cables. A hot swappable BSC is used in a dual-bus system to process the
communication information between two UPS systems.
