● 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
PARALLEL The PARALLEL port transmits parallel signals between racks.
BSC 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 parallel cable is required for a single UPS.
