Physical installation

Warning! Read 'Safety information' on page 5 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. Make sure that the sun will not shine
into the front of the fixture at any time.
The Glare Shield available from Martin (see
'Accessories' on page 55) can help protect
the front of the fixture from the sun.
If the control panel will be exposed to sunlight, install its cover to protect the panel and its display
from heat and UV radiation.

Cooling

The Exterior Projection 500 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 but it needs to dissipate heat externally by convention.
Ensure sufficient ventilation and free airflow around the fixture, especially around the grills on the
back of the fixture, to minimize any reduction in LED output in high ambient 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

The fixture can be mounted at any angle and the yoke can be fastened to a vertical, horizontal or
angled surface, but the sides of the fixture must be vertical when installed (see examples below),
or the fixture's cooling airflow will be affected, leading to excessively high fixture temperature and
reduced light output.
