should be installed alternatively. The spacing between two grounding points of the
same specification is 133.35 mm (5.3 in.), as shown in Figure B-58 (1).
The main grounding point used to connect the module and the cabinet is located at
the back of the upper enclosure frame. The specification is M6, as shown in Figure
