DRMS application description
Only applicable to AS/NZS4777.2:2015.
DRM0-DRM8 are available.
CAUTION
Damage to the inverter due to moisture and dust penetration
Make sure the cable gland has been tightened firmly.
If the cable gland are not mounted properly, the inverter can
be destroyed due to moisture and dust penetration. All the
warranty claim will be invalid.
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.
WARNING
Excessive voltage can damage the inverter!
External voltage of PCI PORT don't over +5V.
