Horizontal sensor
mounting
Take note of the following mounting instructions:
l Mount the bracket first, then the sensor and the source holder
l The arrow cutout in the clamp (source container side) and the
transport lug of the source container must point in the same
direction (A) after mounting
l Make sure that the two clamps (5 and 8) of the bracket are in
parallel. Do this by measuring the distances between the clamps
l To avoid injuries, shorten the threaded rods (1) of the brackets to a
suitable length after mounting
Mount the bracket according to the following assembly drawing:

2 Mounting
Install a protective grid
1 Make sure that the two clamps (5 and 8) of the bracket are in
parallel. Do this by measuring the lateral distances between the
clamps.
2 Tighten the nuts of the threaded rod evenly. Keep the tube
diameter and the stability of the tube material in mind. Avoid
deformation of the tube through an overtightening of the mounting
bracket.
If you have the impression that the tube cannot permanently carry
the weight of the mounting bracket, sensor and source container,
mount a suitable support below the mounting bracket.
3 Shorten the threaded rods after mounting to avoid injuries.
If there are gaps or intervening spaces around the installation, provide
protective fences or grids to keep hands away from the dangerous
area. Such areas must be marked accordingly.
Install a protective grid on both sides of the mounting bracket. A sheet
metal cover or a correspondingly shaped plastic sheet can also be
used.
Corresponding holes for screws of size M5 are provided on the
mounting bracket.
Mount the protective grid according to the following assembly drawing:
