6.9 Connecting the COM PORT
This series inverter has a 8 Pin COM PORT, this port has the function fo demand response
modes, for Australian mode, we can use the 8 Pin COM PORT as inverter DRED
connection, for European modes, we can use the 8 Pin COM PORT as Power Control
Interface(PCI).
6.9.1 Inverter demand response modes-DRMs(Australia only)
This series inverter has the function of demand response modes, We use 8Pin COM PORT
as inverter DRED connection.
6.9.1.1 8Pin socket pin assignment
6.9.1.2 Method of asserting demand response modes
6.9.2 Inverter demand response modes-Power Control Interface(PCI) for EU
This series inverter has the function of demand response modes, We use 8Pin COM PORT
as Power Control Interface(PCI) for European models.
Active power control with a Radio Ripple Control Receiver(RRCR).
