2.3 Protection units
A. RCMU
When inverter'e leakage current exceeds safety requirement, inverter will stop generation
B. Grid abnormal protection
When inverter detects the grid or voltage is out of range , inverter will stop generation.
Inverter will restart to generation automatically when the grid is normal again
C. Ground fault detecting
When ground fault happen , inverter will stop generation automatically and the GFI red LED
will be on to inform customer.
D. Over temperature de-rating
When temperature is higher than internal setting ,inverter will derate the power
automatically
E. Over voltage de-rating
WHen MPPT point is higher then 850V , inverter will derate the power automatically
F. Over current protection
When inverter is abnormal, overter current protection can protect inverter from damange

1. Check the string polarity
2. Make sure the DC switch is OFF,connect the sting to inverter DC side accordingly
3.The string voltage can not be higher than 1000V
4. Check if the connector is fixed well and correctly
5. Check if the PE connection cable and screw is fixed well , check if the communication is
connected well(if needed)
6. Check string connection type , if one string is connected to inverter two MPPT, set inverter
mode as parallel mode(default is independent mode)
7. Switch on DC switch first ,check if the LCD turned on normally , then turn ON AC switch ,
inverter should generate power normally, if any abnormal sound, turn off the AC and DC
switch. If there is alarm on the inverter , check the manual for trouble shooting.
4.5.2 PINs Physical Function Discription：
The DRMs function allocation is shown in below Table:
4.5.3 Enable the DRMs function.
1. Connected the cables as shown below ;
2. Provided the DC Power through the PV Pannel until the LCD is working;
3. Set inverter country code as 02(Australia) in Enter Setting>Set Country Code(password 0001)；
4. Enable DRMs function in Enter Setting>DRMs Control(password 0001);
5. Only DRM0, DRM5, DRM6, DRM7, DRM8 has been defined. Inverter will works as DRM0,
DRM5, DRM6, DRM7, DRM8 when Corresponding switch closure. Their priority is
DRM0>DRM5>DRM6>DRM7>DRM8.

Step 1 Turn on DC switch.
Step 2 Turn on AC switch.
When the solar arrays generate adequate power, the inverter will startup automatically.
Display showing “normal” indicates correct operation.
Step 3: Choose the correct country code. (refer to section 6.3 of this manual)
Notice: Different distribution network operators in different countries have
different requirements regarding grid connections of PV grid connected
inverters.
Therefore, it's very important to make sure that you have selected the correct
country code according to requirements of local authority.
Please consult qualified electrical engineer or personnel from electrical safety
authorities about this.
DASS Tech Co., Ltd is not responsible for any consequences arising out of
incorrect country code selection.
If the inverter indicates any other fault, please refer to part 7——error messages for help.
