Removing the Rubber Rings from the Crimping Module Use scissors to cut off the joints of the rubber rings to remove them. All rubber rings are removed in the same way. (Optional) Installing the Solar Tracker Power Cable 1. A switch-disconnector-fuse or fuse-switch-disconnector with a voltage of no less than 800 V, current of 16 A, and protection type of gM needs to be installed between the SUN2000 and the tracker controller for protection.
Installing AC Output Power Cables • Remove the corresponding rubber rings in strict accordance with the cable diameter, and ensure that the crimping module is not damaged. Otherwise the protection level of the solar inverter will be affected. • 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.

1. Use the MC4 EVO2 PV connectors delivered with the SUN2000. If the PV connectors are lost or damaged, purchase the connectors of the same model. The device damage caused by incompatible PV connectors is beyond the warranty scope. 2. Before connecting DC input power cables, label the cable polarities to ensure correct cable connections.
Installing the RS485 Communications Cable 4.10 1. The RS485 and MBUS communication modes are mutually exclusive. 2. When routing communications cables, separate communications cables from power cables to prevent communication from being affected.
