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.
