4.5 DRMS Connection
DRMS(Demand response enabling device) is used for Australia and New Zealand installation
(also used as remote shutdown function in European countries), in compliance with Australia and
New Zealand safety requirements( or European countries). Inverter integrates control logic and
provides an interface for DRMS. The DRMS is not provided by inverter manufacturer. Detailed
connection of DRMS & Remote Shutdown are shown below:
Step 1.
Screw this plate off from the inverter. See Figure 4.6-1.
