Alignment

You must align the SIRIUS ACT devices before you finally tighten and secure them against
twisting. You can do this in 4 different ways:
1. Alignment on horizontal guide line
2. Alignment with guide line on the arrow of the holder
3. Alignment with spirit level/ruler
4. Alignment on the fixing point
Procedure
Alignment on horizontal guide line
For this purpose, a horizontal line is drawn 18.5 mm above the center point of the 22.5 mm
fixing hole. The holder can be aligned with this line when tightening the fixing screw.
Alignment with guide line on the arrow of the holder
In vertical alignment of the fixing hole, a vertical line is drawn to which the holder is aligned
with the help of the printed arrow.
Alignment with spirit level/ruler
The spirit level is placed on an even surface of the holder. After alignment on the horizontal,
the fixing screw is tightened. Alternatively, a ruler can be used with a range of devices. For
this purpose, all holders must first be roughly aligned under the ruler. Then one holder after
another is precisely aligned with the help of the applied ruler, and fixed with the fixing screw.
After the device has been aligned, you must tighten the fastening screw with a torque of
between 1.0 and 1.2 Nm. The high transformation ratio of the fixing mechanism and the
pointed teeth of the fixing collar provide rugged and long-lasting protection against twisting.
You can then install the contact module and/or LED module(s) as required.
