For CE LVD: The main earth point should be marked with the circled upside down tree. Only one such symbol should appear on your product. This is your main earth bond point.
Any other points you wish to mark as earth should be marked with the uncircled variety of the upside down tree. Refer EN 60065 for symbol - tree is not solid but formed with horizontal lines of decreasing length.

Which symbol is correct for use on a chassis for protective earthing - the upside down tree or the circle upside down tree or the pitchfork?? (Note:- the ground on the back of the box is generally marked "GND" and is screw and locking washer configuration). What is the correct marking to satisfy a NRTL for a marking?
