Grounding
According to the EN50178 requirement, the right side of the device has a protective grounding connection.
Be sure to connect the protection ground cable to this port when installing the inverter.
The user can perform the ground connection according to the on-site condition.
Step1 Remove an appropriate length using a wire Stripper.
Step2 Insert the exposed core wires into the crimping areas of the OT terminal and crimp them
using hydraulic pliers.
Step3 Remove the ground screws from the ground points.

Ensure that the grounding resistance is less than 10Ω.
According to regulations, the secondary protection grounding can't replace the PE
terminal connection of the AC cable. Ensure that both are grounded reliably;
otherwise, fatal injury can occur due to the high voltage.
If the positive pole or negative pole of the PV array is required to be grounded,
then the inverter output (to AC grid) must be isolated by transformer in accordance
with IEC63109-1,-2 standards.
