The ports 5-6, 7-8 and 9-10 are the CT cable connections. Please ensure
the CTs are connected with the correct polarity and the corresponding
grid phase. Also, please note the small arrow inside the CTs, as shown in
Figure 5, shall be pointed towards the Grid (5-6 to La, 7-8 to Lb, 9-10 to
Lc) as shown in Figure 4.
Step 1:
1,2,3 and 4 are the voltage detection ports. Please connect the ports with
the corresponding grid phases (1 to La, 2 to Lb, 3 to Lc, 4 to N) as shown in
Figure 4.
Step 2:

12 and 13 are the auxiliary power source of the meter, 13 should be
connected to the Neutral Wire(N) while the 12 should be connected to
line La on the inverter backup output as shown in Figure 4 and Figure 3.
