7. Remove the locking cap from the AC OUTPUT waterproof cable connector at the inverter
bottom and remove the plug from the locking cap.
8. Route the AC output power cable into the locking cap and the AC OUTPUT connector at the
inverter bottom.
9. Connect the wires of the AC output cable for the SUN2000-33KTL/33KTL-E001 to L1, L2, L3,
and N on the AC terminal block. Secure the screws using a 10 mm socket wrench. Connect the
wires of the AC output cable for the SUN2000-30KTL-A/40KTL to L1, L2, and L3 on the AC
terminal block. Secure the screws using a 13 mm socket wrench. If you connect a ground cable
to the ground point in the maintenance compartment, tighten the ground screw using an M6
torque screwdriver.
5. Insert the exposed core wires into the crimp area of the OT terminal and crimp them using
hydraulic pliers.
6. Wrap the wire crimp area with heat shrink tubing or PVC insulation tape.
If heat shrink tubing is used, put it through the power cable and then crimp the OT terminal.

10.Use a torque wrench with an open end of 52 mm to tighten the locking cap to a torque of 7.5
N·m, and seal the waterproof connector.
• Ensure that the AC output power cable is connected securely. Otherwise, the inverter may fail to
operate or experience a fault that will damage the terminal block. For example, the inverter may
generate heat during operation due to unreliable connection.
• If the nverter 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.
