4.3.2 ECM
●
As a control interface for the entire system, the ECM communicates with each
module and provides a bus for communication between the dry contact card
and the system control card. The ECM ensures equalized output currents
between modules so that load power is equally shared.
●
The ECM provides module working status information to the monitoring
system.
●
The ECM controls the running of a single UPS and a parallel system, and
reports the UPS status information to other monitoring modules.
●
The system provides three types of CAN communication: monitoring CAN
communication, intra-rack parallel CAN communication, and inter-rack
parallel CAN communication.
●
The control module consists of one active ECM and one standby ECM.
●
Hot-swappable, 1 U high.
