1. Keep the screw terminals in the correct status, as shown in the rightmost figures. Connect cables to the
correct terminals and tighten the screws clockwise. Pull the power cables to check that the cables are securely
connected. Check that the screws are in the required status. (Use an M5 torque screwdriver with a torque of
2.0±0.2 N·m.)
2. Select a cable clip based on the cable size. Install the cable clip and use screws to secure the cables. (Use an
M4 torque screwdriver with a torque of 1.2 N·m.)
3. Pull the power cables to ensure that they are securely connected.
In the following figure, the power cable is routed in from the middle.
