To INV Backup output

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:
