Physical installation

Warning! Read 'Safety information' on page 4 before installing the fixture.

Protection from the sun

Important! The fixture's optical system can focus
rays from the sun inside the fixture, causing internal
damage and presenting a fire hazard. Damage can
be caused whether the rays come from directly in
front or from the side of the front glass (see drawing
on right). Make sure that the sun will not shine into
the front of the fixture at any time.

Cooling

The Exterior Projection Pro Compact has a thermal protection system. If temperatures inside the
fixture exceed safe levels, it regulates LED output to protect components.
The fixture has internal forced air cooling and an external IP-rated cooling fan. Ensure sufficient
ventilation and free airflow around the fixture, especially around the grill on the back of the fixture, to
minimize any reduction in LED output due to high temperatures.

Protection from moisture

If there is a break or cut at any point in a cable (for example at a
connection point), and if this is exposed to water, moisture can be
drawn up the inside of the cable due to the vacuum effect of
temperature fluctuations during operation. Ensure that the fixture is
protected from the entry of water via cables by using IP66-rated
connectors or junction boxes, or by protecting connectors with
weatherproof housings. Make sure that all cables open into dry
areas.
See illustration on right. Create a drip loop before cable glands to
reduce any tendency for glands to be constantly immersed in water.

Mounting the fixture

Important! See illustration on right. Do not mount the fixture
with the front glass angled at more than 70° from horizontal
in any location where rain or dripping water may be present.
At angles greater than 70°, water can collect on the front
glass, causing damage if it freezes and interfering with
projections.
The fixture can be mounted at any angle (apart from the 70°
limit described above) and the yoke can be fastened to a
vertical, horizontal or angled surface. Do not stand the fixture
freely on a surface or leave it where it can be moved or fall
Max. 70°
over.
Installing on a rigging truss
It is possible to install the fixture temporarily on a rigging truss or similar support. If you do this, fasten
two approved rigging clamps to the mounting yoke with two grade 8.8 strength M12 bolts fastened
through holes B in the mounting yoke base (see illustration at bottom of page) and suspend the fixture
