Use a horizontal ruler to check the levelness of two horizontal borders on the top of the bottom
frame. If the bottom frame is out of the horizontal, add leveling washers below the insulation plate
to level the bottom frame.
Check the
insulativity
Check the resistance of the bottom frame.
 If the resistance is equal to or bigger than 5MΩ, the bottom frame is insulated from the ground.
You can fix the cabinet then.

bottom frame and ensure that it is correctly installed.
