If the R-in+ interface is disconnected from the R-in-interface, the device will trigger an EPO
alarm to shut down.

WARNING
Only qualified professional can use R-in+ and R-in-interface.
3.6.8 DMR0 port
According to the Australian certification requirements for the Inverter demand response
modes (abbreviated as DRM) function, the grid-connected equipment incorporated into the
Australian grid must be equipped with a DRM device. Therefore, the PWS2-30M-EX device
shipped to Australia must have a built-in DRM device, while shipments to other countries,
optional DRM device. At present, the DRM device built into the PWS2-30M-EX can only
implement the DRM0 function as shown in the following figure.
Fig. 3-8 DRM function selection table
When the PWS2-30M-EX has a built-in DRM device, the customer can enable or disable
the DRM0 function by setting the contents of the 0x0148 address register to 2 or 0.
If the DRM0 function is enabled, a resistor with a resistance of 15k
Ω
and power greater
than 0.1W must be connected between the R-in+ interface and the R-in-interface. If the
resistor is short-circuited or open circuited, the PWS2-30M-EX device will report a fault
within 2 seconds and shut down.
