4.2 Overhead Installation
V. 01 – 11/09/2018
HQDB10001/HQDB10002
When hung, the device must always be secured with a
secondary attachment e.g. a safety cable (not incl.).
Secondary Attachment
Hanger
Where a hanger is provided, the bearing parts of the hanger
shall be capable of supporting ten (10) times the weight of
the luminaire without permanent deformation and shall be
manufactured from non-combustible materials such as steel
or its equivalent.
Accessories
The design of the luminaire shall be such that removable
accessories, e.g. colour frames and barn doors, when
properly inserted, cannot fall out of the luminaire.
Secondary Suspension
A secondary suspension shall be provided for the luminaire,
except where the luminaire is arranged for floor mounting or
if it is intended for handheld use. The secondary suspension
shall be designed and mounted in such a way that in the
event of a failure of the primary suspension, no part of the
luminaire can fall. The secondary suspension must withstand
a 30 cm vertical drop for 30 times.
a
safety cable
Never stand directly below the device when it is being
mounted, removed or serviced. Have a qualified technician
check the device once a year and once before you bring it
into service.
Overhead mounting requires extensive experience:
calculating workload limits, determining the installation
material to be used... Have the material and the device itself
checked regularly. Do not attempt to install the device
