In order to improve the corrosion resistance of the grounding terminal, we
recommend that the External grounding terminal should be coated with
silica gel or paint for protection after the installation of the grounding cable.
Important:
Figure5.9 fix the cable
Figure5.8 strip wire
After crimping the terminal to the wire, inspect the connection to ensure the
terminal is solidly crimped to the wire.
5) Remove the screw from the heat sink ground point.
6) Use the screw of the ground point to attach the grounding cable.
Tighten the screw securely. Torque is 3Nm (as shown as in Figure 5.9).
