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.
