Page 10: Installing The Pe Cable
Installing the PE Cable • It is recommended that the PE cable be connected to a nearby PE point. Connect the PE points of all SUN2000s in the same PV array to ensure equipotential connections to PE cables. • To enhance the corrosion resistance of a ground terminal, you are advised to apply silica gel or paint on it after connecting the PE cable. - Page 11 3. Remove the crimping modules that are bound in the maintenance compartment and save them properly for future use. For some models, a three-hole rubber plug is bound in the maintenance compartment. After removing the rubber plug, save it properly for future use. Crimping module (Optional) Replacing the Crimping Module...
- Page 12 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.

Page 13: Installing Ac Output Power Cables
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. - Page 14 Single-Core Cable The 32–36 mm cable is supported only (five rings) by some models. Refer to the (four rings) corresponding label to get the (three rings) supported size.
