5.3 Installing the PE Cable
Context
Proper grounding is helpful for resisting the impact of surge voltage and improving the
electromagnetic interference (EMI) performance. Before connecting the AC power cable,
DC power cable, and communications cable, connect the PE cable to the PE point.
It is recommended that the PE cable of the SUN2000 be connected to a nearby PE point.
Connect the PE points of all SUN2000s in the same array to ensure equipotential
connections to PE cables.
Procedure
Step 1
