6.8.2 Inverter demand response modes-Power Control Interface(PCI) for EU
This series inverter has the function of demand response modes, We use 8Pin COM
PORTas Power Control Interface(PCI) for European models.
Excessive voltage can damage the inverter! External voltage of PCI
PORT don't over +5V.

6.9 Earth Fault Alarm
The inverter complies with AS/NZS 5033.The installer does not need to perform any
additional actions, as this is already set up.When the Earth fault occurs,the Red LED will
light up.
The buzzer in the inverter will keep ringing unless the fault condition is cleared(This
function is only avilable for Australia and New Zealand).
