Congratulations on having purchased a Coemar product. You have assured yourself of a fixture of the highest

4. Installation
4.1 Mechanical installation
LEDko EXT Basic may be hung from an appropriate structure in any position or on tripod. If hanging the fixture
from a lighting truss or similar, we recommend the use of an appropriate clamp “A”, as shown in the following
diagram.
Always ensure that your support structure
and fixing (bolts, clamps, etc…) are rated to
support the weight of the fixture.
4.2 Safety chain
When hanging LEDko EXT Basic it is recommended to use a safety chain, as required by current legislation. The
safety chain must pass through the handles of the unit and then attached to the structure.
If using steel cables and chains not Coemar’s production, make sure they are suitable to support the weight of
the unit according to normative UL/ETL (required: the weight of 6 complete devices for at least one hour).
