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.
Description
The PARALLEL port transmits parallel signals between racks.
The BSC port is used in a dual-bus system to synchronize
output frequencies and phases between UPS systems,
ensuring that two buses can switch with each other.
BSC cables are hot-swappable.
NO TE
No parallel cable is required for a single UPS.
