6.5 Fastening of the safety
coupling
Take special care when attaching and
fastening down the apparatus. If the
equipment must be fastened to a concrete
surface, plugs must be used with a
minimum traction force of 300dN each. For
a metal surface use screws with a diameter
of at least 8mm and of an appropriate
length. The fastening system must be
capable of supporting at least 4 times
the weight of the entire equipment (PTZ,
supports and adapters).
The product is equipped with a safety coupling to
secure the product to a second fixing point through
a safety chain or cable.
Position the safety coupling and fix it with the screw
and the washer supplied as shown in the figure (Fig.
8, page 12).
Use an external anchor point to fix the
chain or the safety cable to the unit
support surface. Choose a chain or safety
cable capable of supporting 4 times the
weight of the unit, including its brackets
and adaptors.
Pay attention to the fixing. Tightening
torque: 4.5Nm (±0.2Nm).
Apply thread-locker into the holes for
screws (Loctite 243®).
