2.4.2.2 ECM
The CM provides two active/standby energy control modules (ECMs). Each ECM provides
one BSC port and one parallel port, as shown in
Figure 2-11
ECM
To connect UPSs in parallel, use a parallel cable to connect the parallel ports on the ECMs on
the two UPSs. A hot swappable BSC is used in a dual-bus system to process the
communication information of two UPS systems.
describes the functions of the
ECMs.
