8. Assembly Instructions

8.1 SM1-PL and SM1-OX

a) Drill the holes of the mounting bracket at F= 4.5 mm, with a center distance of 72 mm.
b) Use the stainless steel washers supplied with the product in order to preserve the box's casing
c) With the door closed, the distance between the polar plate and the suction cup should ideally be 0.
The polar plate is flexible which makes it possible to compensate for function
d) The bending radius of the cable must be greater than 50 mm.
e) Use tamper-proof screws

8.2 SM2

a) Drill the holes of the mounting bracket at F= 6.5 mm, with a center distance of 163 mm.
b) c) d) e) Same as in §7.1
f) The transmitter can be equipped with the EPB handle. The advantage is to ensure a pulling force in
the axis of the suction cups and thus obtain the maximum force by avoiding the leverage effect.
