4.2 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.
4.3 Opening the Maintenance Compartment Door

protective measures to prevent rain or snow from entering the maintenance compartment.

compartment door.
