The user must make two ground connections :one shell grounding, and one
equipotential grounding .This prevents electric shock.

Step 2. Strip the grounding cable insulation(lenhth”L2), insert the
stripped cable into the ring terminal, and then clamp it.

Step 1. Prepare a one-core cable (12AWG), and then find the ground
terminal in the accessories.

Step 3. Insert the stripped cable into OT terminal and tighten the terminal
with a terminal crimping tool.

Step 5: Finally, find the corresponding COM, METER, CT, DRM poets on the
inverter and insert the communication cable into the corresponding ports.
Note: If the PV end of the inverter is not connected with earth , the inverter
will turn on a red light Inspect and report ISO Fault .This inverter complies
with IEC 62109-2 clause 13.9 for earth fault alarm monitoring.
The ground wire port of X1-Hybrid G4 M series inverter has been
connected, and the D series needs to be wired according to the
following steps.
