As a control interface for the entire system, the ECM communicates with each
module and provides a bus to communicate with the dry contact card. The
ECM ensures equalized output currents between modules so that load power
is equally shared.
Provides module running information for the MDU.
Controls the running of a single UPS5000 and a parallel system, and reports
the UPS5000 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.
