(Optional) Connecting Battery Cables
Prerequisites
- Battery short circuits may cause personal injury. The high transient current generated by a short circuit may release a surge of power and cause fire.
- Do not connect or disconnect the battery cable when the SUN2000 is running. Failing to do so may cause electric shocks.
- Before connecting the battery cables, ensure that the DC switch on the SUN2000 and all the switches connecting to the SUN2000 are OFF, and the SUN2000 has no residual electricity. Otherwise, the high voltage of the SUN2000 and battery may result in electric shocks.
- If no battery connects to the SUN2000, do not remove the watertight cap from the battery terminal. Otherwise, the IP rating of the SUN2000 will be affected. If a battery connects to the SUN2000, set aside the watertight cap. Reinstall the watertight cap immediately after removing the connector. The high voltage of the battery terminal may result in electric shocks.
A battery switch can be configured between the SUN2000 and the battery to ensure that the SUN2000 can be safely disconnected from the battery.
- Do not connect loads between the SUN2000 and the battery.
- The battery cables should be connected correctly. That is, the positive and negative terminals of the battery connect to the positive and negative battery terminals on the SUN2000 respectively. Otherwise, the SUN2000 may be damaged, or even a fire could happen.
- During the installation of the SUN2000 and battery, the positive or negative terminal of the battery will be short-circuited to ground if power cables are not installed or routed as required. In this case, an AC or DC short circuit may occur and damage the SUN2000. The caused device damage is not covered under any warranty or service agreement.
- The cabling distance between the battery and the SUN2000 should be less than or equal to 10 meters, and within 5 meters is recommended.
Procedure
- Assemble the positive and negative connectors by referring to Connecting DC Input Power Cables.
- The battery voltage will result in serious injury. Use dedicated insulation tools to connect cables.
- Ensure that cables are correctly connected between the battery terminal and the battery switch, and between the battery switch and the SUN2000 battery terminal.
Cables with high rigidity, such as armored cables, are not recommended as battery cables, because poor contact may be caused by the bending of the cables.
- Insert the positive and negative connectors into corresponding battery terminals on the SUN2000.
After the positive and negative connectors snap into place, pull the battery cables back to ensure that they are connected securely.
