the back of the frame.
b) Each modules needs to be fastened by
at least 4 points on two opposite sides.
c) M8 x 1.25 (5/16”) bolts and nuts should
be used. The yield strength of bolts and nuts
should not be less than 450 MPa, and the reco-
mmended torque is 16-20 Newton meters.
d) The outer flat washer needs to use M8
(A2-70), a stainless steel (SUS304) flat washer
with an outer diameter of 20±2 mm and a
thickness of 1.1-1.2 mm; the corresponding
