Connecting a ground cable 

 

 

 

To enhance the corrosion resistance of the ground terminal, apply silica gel or paint on the ground 
terminal after connecting the ground cable.

5.3 Connecting AC Output Power Cables 

Prerequisites 

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. 

Context 

 

If you connect a ground cable to the ground point on the chassis shell in a scenario with 
no neutral wire, you are advised to use a three-core (L1, L2, and L3) outdoor cable as the 
AC output power cable for the SUN2000-33KTL-A/36KTL. 

 

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 as the AC output power cable for the SUN2000-33KTL-A/36KTL. 

 

If you connect a ground cable to the ground point on the chassis shell in a scenario with a 
neutral wire, you are advised to use a four-core (L1, L2, L3, and N) outdoor cable as the 
AC output power cable for the SUN2000-33KTL-A/36KTL.
