Alien LED Downlight user manual
Physical installation
Warning! Read "Safety Information" on page 3 before installing the Alien LED Downlight.
The safety and suitability of installation location, anchoring method, mounting hardware
and electrical installation is the responsibility of the installer. All local safety regulations
and legal requirements must be observed when installing and connecting the Alien LED
Downlight. Installation must be carried out by qualified professionals only.
The ambient temperature around driver units and transformers must not exceed 40° C
(104° F). The ambient temperature around luminaires must not exceed 45° C (113° F).
Provide ventilation as necessary to ensure these levels are not exceeded. Leave at least
50 mm (2.0 in.) of free space and allow airflow around driver units, transformers and
luminaires.
Contact your Martin™ supplier for assistance if you have any questions about how to
install this product safely.
Location and orientation
Warning! Install luminaires, transformers and driver units at least 50 mm (2 in.) away from
thermal insulation material and well away from highly flammable materials.
Downlight luminaires are designed to be installed in a ceiling or wall recess with a ceiling or wall
thickness of 5 - 22 mm (0.2 - 0.85 in.).
Allow for service access to driver units and transformers.
Important! When installing luminaires in a row or group, ensure homogenous light
distribution by orienting them all in the same direction (i.e. with the luminaire wiring
facing in the same direction on all luminaires).
Mounting and fastening luminaires
Luminaires can be fixed into position by two methods:
• A tank nut on the 2-inch BSP thread on the luminaire housing, for which a 63 mm (2.5 in.)
diameter cutout in the ceiling or wall is required. Access to the ceiling or wall recess is required
in order to tighten the tank nut. The tank nut mount is recommended in indoor and outdoor
installations.
• A plasterboard clip system, for which a 70 mm (2.8 in.) diameter cutout in the ceiling or wall is
required. Access to the ceiling or wall recess is not required in order to fasten the luminaire, as
the luminaire is pushed into position from outside the recess and the wing clips spring open to
hold the luminaire in position. The plasterboard clip system is recommended in indoor
installations only.
In both methods, high-pressure nitrile O-rings ensure a gas and vapor seal when the luminaire is
correctly installed.
Tank nut mounting
1. Use a hole saw mounted on a power drill to drill a 63 mm (2.5 in.) diameter circular hole in the
mounting surface.
2. Push the luminaire up into the hole, install a suitable washer and nut on the 2-inch BSP thread
in the luminaire housing, and tighten the nut to secure the luminaire.
