5.6.2 Installing COM Communications Cables
Context
● The COM communications port transmits CAN signals and dry contact
protection signals.
● CAN and dry contacts establish a channel for communication between the
Smart PCS and the ESS battery rack and for fast protection. If the ESS is
faulty, the Smart PCS will receive a shutdown command immediately.
● If one battery rack corresponds to one Smart PCS, the Smart PCS is directly
connected to the ESS. If one battery rack corresponds to multiple Smart PCSs,
these Smart PCSs need to be connected in hand-in-hand mode.
