The fixture has to be installed out of the reach of the prying fingers of the public.
Danger of fire !
When installing the device, make sure there is no highly inflammable
material (decoration articles, etc.) in a distance of min. 1 m.
CAUTION!
Use 2 appropriate clamps to rig the fixture on the truss.
Follow the instructions mentioned at the bottom of the base.
Make sure that the device is fixed properly! Ensure that the
structure (truss) to which you are attaching the fixtures is secure.
The fixture can be placed directly on the stage floor or rigged in any orientation on a truss without altering its
operation characteristics.
For securing a fixture to the truss, install a safety wire that can hold at least 10 times the weight of the fixture.
Use only the safety wire with screw-on carabineer. Pull the safety wire through the safety attachment point
on the bottom of the base and around the truss as shown on the pictures below.
