2.5 DRED and Remote Shutdown Device Connection
A DRED (demand response enabling device) is required for installation in Australia and New
Zealand (and can also be used for remote shutdown in European countries), in compliance with
Australia and New Zealand safety requirements (or those of European countries). The inverter
includes the required control logic and DRED interface, but the DRED itself is not provided by the
inverter manufacturer.
Connection details for DRED and remote shutdown are shown below:
NO.

Note: DRED should be connected via the "DRED Port" as the figure shows.
Step 1
Step 2
1. Unplug the 6-pin terminal and disconnect
the resistor.
2. Remove the resistor and retain the 6-pin
terminal for the next step.
Note: The 6-pin terminal in the inverter has
the same pinout as the DRED. Please
leave it in the inverter if no external
device is connected.
2.6 Earth Fault Alarm Connection
The EM series inverter complies with IEC 62109-2 13.9. The fault indicator LED on the inverter
cover will light up and the system will email fault information to customer.
The inverter should be installed at eye level for convenient maintenance.
2.7 SEMS Portal
