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.
For a single UPS, the parallel cable is not needed.

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.
