6.12 DI Connection
DRM and Ripple Control support only one function at the same time.
DRM
The inverter supports the demand response modes as specified in the standard AS/NZS
4777. The inverter has integrated a terminal block for connecting to a DRED.
After the connection, the DRED assert DRMs by shorting together terminals as specified in
the table below.
table 6-4 Method of Asserting DRMs
Mode
Asserted by Shorting Terminals
DRM0 R & C
DRM1 D1/5 & C
DRM2 D2/6 & C
DRM3 D3/7 & C
DRM4 D4/8 & C
DRM5 D1/5 & R
DRM6 D2/6 & R
DRM7 D3/7 & R
DRM8 D4/8 & R
The modes from DRM0 to DRM8 are supported by the inverter and the information is
marked on the label located in the top of COM terminal.
Wiring between the inverter and the DRED is as follows.
The switches that need to be closed in the state of DRM0 ~ DRM8 are shown in the table
below.
Demand Response Mode Operational Instruction Switch state
DRM0 OI0 Close S1 and S5
DRM1 OI1 Close S1
DRM2 OI2 Close S2
DRM3 OI3 Close S3
DRM4 OI4 Close S4
DRM5 OI5 Close S5
DRM6 OI6 Close S6
