contactors to enable/disable the load. For high
voltage AC230V. PIN2 is reserved for safety
regulations.
2 NC Reserved PIN
3 DO1- Dry contact
4 GND
Power supply

6 RSD_12V
Controls the RSD
modules externally.
Reserved. Connects to RSD_12V and 12V_S to
control the RSD module rapidly.
7 GND

DRED or RCR
Optionnal function.
• DRED (Demand Response Enabling
Device): the inverter satises the Australian
DERD certication and o󰀨ers DRED signal
controlling ports.
• RCR (Ripple Control Receiver): In Germany
and some other European regions, grid
companies use Ripple Control Receiver
to convert grid dispatching signals into dry
contact mode for transferring. And the power
station receives grid dispatching signals
through dry contact communication mode.
