To enhance the corrosion resistance of the ground terminal, apply silica gel or paint on the ground
terminal after connecting the ground cable.
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 SUN2000-29.9KTL/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
SUN2000-29.9KTL/33KTL-A/36KTL.
