Precautions

A three-phase AC switch needs to be configured outside the AC side of the SUN2000. To ensure that the SUN2000 can safely disconnect from the power grid under abnormal conditions, select an appropriate overcurrent protection device according to local power distribution regulations.

Do not connect loads between the SUN2000 and the AC switch.

The SUN2000 is integrated with a comprehensive residual current monitoring unit (RCMU) to distinguish fault current from residual current. Upon detecting that the residual current exceeds the threshold, the SUN2000 immediately disconnects from the power grid.
NOTE:
  • If an AC switch that can detect residual current is installed outside the SUN2000-50KTL-M0, the residual current value to trigger the switch should be greater than 550 mA.
  • If an AC switch that can detect residual current is installed outside the SUN2000-60KTL-M0, the residual current value to trigger the switch should be greater than 660 mA.
  • If an AC switch that can detect residual current is installed outside the SUN2000-65KTL-M0, the residual current value to trigger the switch should be greater than 720 mA.

Wiring Precautions

Ensure that the SUN2000 PE cable is securely connected. Otherwise the repair of the built-in PID would be affected.

  • The ground point on the enclosure is preferred to connect to the PE cable for the SUN2000.
  • The ground point in the maintenance compartment is mainly used for connecting to the ground cable included in the multi-core AC power cable.
  • There are two ground points on the enclosure and you only need either of them.
  • It is recommended that the ground cable be connected to a nearby ground point. For a system with multiple SUN2000s connected in parallel, connect the ground points of all SUN2000s to ensure equipotential connections to ground cables.

Cable Specifications

  • For the SUN2000-50KTL/60KTL-M0:
    • If you connect a ground cable to the ground point on the enclosure in a scenario with no neutral wire, you are advised to use a three-core (L1, L2, and L3) outdoor cable.
    • If you connect a ground cable to the ground point in the maintenance compartment in a scenario with no neutral wire, you are advised to use a four-core (L1, L2, L3, and PE) outdoor cable.
    • If you connect a ground cable to the ground point on the enclosure in a scenario with a neutral wire, you are advised to use a four-core (L1, L2, L3, and N) outdoor cable.
    • If you connect a ground cable to the ground point in the maintenance compartment in a scenario with a neutral wire, you are advised to use a five-core (L1, L2, L3, N, and PE) outdoor cable.
  • For the SUN2000-65KTL-M0:
    • If you connect a ground cable to the ground point on the enclosure, you are advised to use a three-core (L1, L2, and L3) outdoor cable.
    • If you connect a ground cable to the ground point in the maintenance compartment, you are advised to use a four-core (L1, L2, L3, and PE) outdoor cable.
  • You need to prepare OT-M10 terminals that match the cables.

The values in this table are valid only if the PE cable and AC power cable use the same conductor material. If this is not so, the cross-sectional area of the PE cable conductor is to be determined in a manner which produces a conductance equivalent to that which results from the application of this table.

Installing the PE Cable

  1. Crimp an OT terminal.
  2. Secure the PE cable using the ground screw.

    Figure 5-7 Connecting a PE cable

  3. (Optional) To enhance the corrosion resistance of a ground terminal, apply silica gel or paint around the terminal.

Installing the AC Output Power Cable

  1. Remove the locking cap from the AC OUTPUT cable gland and then remove the plug.
  2. Route the cable through the cable gland.

    1. Select appropriate rubber fittings based on the outer diameter of the AC power cable to ensure proper sealing.
    2. To avoid damaging the rubber fitting, do not route a cable with a crimped OT terminal directly through the rubber fitting.
    3. Adjusting a cable when the thread-lock sealing nut is tightened will shift the rubber fitting, which will affect the Ingress Protection Rating of the device.

    Figure 5-8 Routing a cable

  3. Remove an appropriate length of the jacket and insulation layer from the AC output power cable using a wire stripper.

    Ensure that the jacket is in the maintenance compartment.

  4. Crimp an OT terminal.
  5. Land the AC output power cable in the terminal block, and tighten the nuts with a torque wrench that has an extension rod.

    • Ensure that AC terminations provide firm and solid electrical connections. Failing to do so may cause SUN2000 malfunction and damage to its terminal block, even starting thermal events. Any SUN2000 damaged due to weak termination will result in revocation of product warranty.
    • When connecting a PE cable, secure the screws using a socket wrench with an extension wrench longer than 200 mm.
    • Sufficient slack should be provided in the PE cable to ensure that the last cable bearing the force is the PE cable when the AC output power cable bears pulling force due to force majeure.

    NOTE:

    The cable colors shown in figures are for reference only. Select an appropriate cable according to the local standards.

  6. Tighten the cable gland.
  7. Clear debris from the maintenance compartment.

    Ensure that there are no cable residues, scraps, or conductive dusts in the maintenance compartment.
