4.4 Rigging the xture
A structure intended for installation of the xture(s) must safely hold weight of the xture(s) placed on it. The
structure has to be certicated to the purpose.
The xture (xtures) must be installed in accordance with national and local electrical and construction codes
and regulations.
For overhead installation, the xture must be always secured with a safety wire
that can bear at least 10 times the weight of the xture
When rigging, derigging or servicing the xture staying in the area below the installation place, on bridges,
under high working places and other endangered areas is forbidden.
The operator has to make sure that safety relating and machine technical installations are approved by an ex-
pert before taking into operation for the rst time and after changes before taking into operation another time.
The operator has to make sure that safety relating and machine technical installations are approved by a skilled
person once a year.
Allow the xture to cool for ten minutes before handling.
IMPORTANT! OVERHEAD RIGGING REQUIRES EXTENSIVE EXPERIENCE, including calculating working
load limits, installation material being used, and periodic safety inspection of all installation material and the
projector. If you lack these qualications, do not attempt the installation yourself, but use a help of professional
companies.
CAUTION: Fixtures may cause severe injuries when crashing down! If you have doubts concerning the safety
of a possible installation, do not install the xture!
The xture has to be installed out of the reach of public.
The xture must never be xed swinging freely in the room.
Danger of re !
When installing the device, make sure there is no highly inammable
material (decoration articles, etc.) in a distance of min. 0.5 m.
CAUTION!
Use an appropriate clamp to rig the xture on the truss.
Make sure that the device is xed properly!
Sucient distance between the xture and surrounding walls has to be
kept to ensure air circulation round the xture.
For securing the xture to the truss, install a safety wire which can bear at least 10 times the weight of
the xture. Use only the safety wire with snap hooks with screw lock gate. Fasten the safety wire around the
truss and the mounting bracket in a suitable position so that the maximum fall of the xture will be approximately
20 cm.
