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).
Information
DRMS application description
Only applicable to AS/NZS4777.2
DRM0, DRM1, DRM2, DRM3, DRM4, DRM5, DRM6, DRM7,
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.
