2) Use a ground cable the same size as the power cable or larger.
3) Pass the cables through the controller’s wiring port to accomplish the wiring work. At the wiring port,
use a cable clamp appropriate to ensure the port satisfies protection class IP54 or better.
4) Connect the power cable to the terminal block. The screws for connecting the power supply ground
are different from those for the power supply cable connection terminals, so take care not to confuse
them. The recommended tightening torque is 1.0 N⋅m.
