Installation procedures
4.9 Suspending the projector from a truss
WARNING: It is the responsibility of the installer to suspend the reinforcement frame in a safe and
secure fashion. Safety cables must be applied according to local regulations and standards. Safety
cables must be dimensioned for the applicable load and no drop distance is allowed or must be
limited as much as possible.
WARNING: When the projector is suspended from a truss, a minimum of four (4) clamps must be
used to secure the projector. The clamps must be fixed to the projector frame. Use clamps and a
truss which is capable of handling five (5) times the complete load of the system).
About the reinforcement frame
A reinforcement frame has been provided to the XDM projector to make the projector more rugged and handy.
Furthermore, while the projector is not foreseen to be suspended from the ceiling, the multifunctional frame
allows the projector to be suspended from a truss. This can be done either in a upright or sideways position.
Take into account the tilt ranges of the projector when mounting the projector.
Installation requirements for projector suspension
The projector can be suspended from a truss by using the reinforcement frame. While doing so, take the
following requirements into account:
•
You can only use swivel coupler double clamps for truss beams. The number of clamps required depends
on the types of clamps used. Always make sure you use at least four clamps: two clamps at two opposed
sides of the frame.

•
Take into account the total weight of projector and frame suspended from the truss. For the XDM, the
working load limit for each clamp must be bigger than 189 kg (417 lbs).
•
The clamps can only be placed on the round profiles of the reinforcement frame. It is not allowed to mount
clamps on the rectangular brackets of the reinforcement frame.
•
Mount the clamps and safety cables on the longest bars on the upper side of the reinforcement frame (the
side facing the truss).
•
It is not allowed to suspend the projector itself, only the reinforcement frame can be suspended.
•
Single point hangers and "single point of connection" suspension cannot be used.
How to suspend from a truss
1.
Measure the distance between the two used support bars of the truss beam, using the center tube as
reference.

2.
Install the rigging clamps on the side of the projector frame that will face upwards. Turn the projector if
necessary. Install the rigging clamps, according the measured distance and secure this position. Ensure
that the rigging points are symmetrically lined up, so that the projector will hang in balance.
