Connecting the AC Output Power Cable

Connecting the AC Output Power Cable

Precautions

A three-phase AC switch needs to be installed on the AC side of the SUN2000. To ensure that the SUN2000 can safely disconnect itself from the power grid when an exception occurs, select a proper overcurrent protection device in compliance with 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. Once detecting that the residual current exceeds the threshold, the SUN2000 immediately disconnects itself from the power grid.

  • If the external AC switch can perform earth leakage protection, the rated leakage action current should be greater than or equal to 100 mA.
  • If multiple SUN2000s connect to the general residual current device (RCD) through their respective external AC switches, the rated leakage action current of the general RCD should be greater than or equal to the number of SUN2000s multiplied by 100 mA.
  • A knife switch cannot be used as an AC switch.

Procedure

  1. Connect the AC output power cable to the AC connector.

    Figure 5-4 Stripping requirements
    • Ensure that the cable jacket is inside the connector.
    • Ensure that the exposed core wire is totally inserted into the cable hole.
    • Ensure that AC terminations provide firm and solid electrical connections. Failing to do so may cause SUN2000 malfunction and damage to its AC connectors.
    • Ensure that the cable is not twisted.

    NOTE:

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

  2. Connect the AC connector to the AC output port.

    Ensure that the AC connector is connected securely.

  3. Check the route of the AC output power cable.

Disconnection

Disconnection can be performed in reverse order.
