Step 8 Connect the AC output power cable to the AC terminal block, and then tighten the nut using a
13 mm socket wrench with an extension rod to a torque of 8 N·m. If you connect a ground
cable to the ground point in the maintenance compartment, tighten the ground screw using a
10 mm socket wrench with an extension rod to a torque of 5 N·m.
Ensure that AC terminations are secured. Failure to do so may cause the SUN2000 to
malfunction or cause damage to its terminal block from issues such as overheating.
If the SUN2000 is insecurely installed and the AC output power cable bears the pulling
force, ensure that the last cable bearing the force is the PE cable.
