The PE cable is a single-core outdoor copper cable with a conductor cross-sectional
area of at least 10 mm

.
−
Use cables that have the same diameter as the AC output cable, and ground the PE
terminal on the AC connector and the ground screw on the enclosure respectively.
In some countries and regions, additional ground cables are required for the SUN2000.
In this case, use cables that have the same diameter as the AC output cable, and ground
the PE terminal on the AC connector and the ground screw on the enclosure respectively.
Procedure
Step 1
Crimp the OT terminal.
Pay attention not to damage the core wire when stripping a cable.
The cavity formed after crimping the conductor strip of the OT terminal needs to wrap the
core wire completely. The core wire needs to contact the OT terminal closely.
Wrap the wire crimping area with the heat shrink tubing or the PVC insulation tape. The
following figure uses the heat shrink tubing as an example.
When using the heat gun, protect devices from being scorched.
