A connecting method of DRM connection
The INVERTER supports the DRM (Demand Response Mode) function as specified in
AS 4777.2 2015.
The terminal block inside the INVERTER is used for connecting to a demand response
enabling device (DRED). The DRED asserts DRMs. The INVERTER detects and initiates
a response to all supported demand response commands within 2s. The following table lists
the DRMs supported by the INVERTER. (DRM 3 and DRM7 will supply or sink reactive power.)
