Line according to the left and right side of the installation plate. The meeting point of the extended line is
the center of the hole. Another method is by putting measuring tape at position as shown in the diagram
above. The hole center is obtained by measuring the distance namely 150 mm for left and right hole
respectively ( Z20***, XZ20***, Z25***, XZ25***, Z35***, XZ35***, Z42***) or 210 mm for left hole and
150 mm for right hole ( Z50***, XZ50***, Z71*** ).
