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.
