Mount the lower L-shaped mounting bracket at the desired height in the lower part. Tighten the M4
screws with a tightening torque of 2 Nm and the M3 screws with a tightening torque of 1.2 Nm.

Mount the C-shaped mounting bracket at the desired height. The recommended distance for the C-
shaped mounting bracket depends on the device; it is approximately 1/4 the length of the light curtain.
This distance is measured from the head surface or end part of the light curtain. Tighten the M4 screws
with a tightening torque of 1.2 Nm.
Ä
Position the upper clamping jaw of the C-shaped mounting bracket by screwing on the M3 screw. Do
not completely tighten the screw.
Ä
Insert the device in the lower seat of the L-shaped mounting bracket with a slight incline. To do this,
use the corresponding lateral slot of the profile. Turn the device so that it snaps into the upper clamping
jaw of the C-shaped mounting bracket.
