Close the controller cover and make sure that the cover screws are tight to keep the environmental rating of the
enclosure.
After the power connections are made, install the high-voltage barrier. Make sure that the high-
voltage barrier is correctly put on the enclosure guides and fixed to the main PCBA. Make sure that
the lower part of the high-voltage barrier (soft rubber lip) is correctly installed and has no
deformation. Refer to Figure 11.
Close the controller cover. Tighten the cover screws with 2 Nm (17.70 lbf-in) torque. Refer to
Figure 7 on page 14.
