Consult an electrician if you have any doubts about the proper wiring connection during your installation.
Data Cables
Data linking is required for synchronized operation as well as DMX controller operation. The Spectrum
fixtures are equipped with two 24 AWG data cables that exit the fixture through a cable gland. Both cables
are equipped with XLR connectors. The locking 3-pin male is for data input and the 3-pin female is for data
output. The "DMX Primer" in the Appendix section details more information about wiring. In short, a 3-pin
connector is wired pin-1 to (ground), pin-2 to (signal) and pin-3 to (hot).
Use RS-485 data cables designed for outdoor use.
(24 AWG) for runs up to 1000 feet or 300 meters
(26 AWG) for runs up to 1640 feet (500 meters)
Currently, neither the data cables nor the power cable is weather rated. Consider changing these for
exterior weather rated equivalents. In addition, follow the same "Safety Precautions" as listed in the section
above "Power configuration".
Lamp Alignment How-To
Often, after a new installation of a lamp, you will find that there is an uneven field of light or what is referred
to as a hot spot. This is due to the most intense point of the lamp source not being positioned optimally
within the reflector. There are three lamp alignment screws
provided at the base of the fixture. Turning these screws
allow you to optimize the projection quality of the spot as
well as the overall intensity of the beam.
1)
Project a white spot against any flat surface.
Preferably the surface should be white or pastel in
color.
2)
Turning the lamp alignment screws, try to position the hot spot in the center of the
beam as best as possible. This could require many attempts on your part. It is
advisable to even out the screws prior to lamp alignment as described in the
illustration.
3)
Once the hot spot is in the center of the spot, do your best to turn all screws equally as
to affect movement up or down within the reflector.
4)
As you move in and out of optimum lamp focus, you will see the hot spot either get wider
or narrower. The goal is to either totally diminish the hot spot by having it widen and spread across
the entire spot or moving the hot spot so that it covers as much of the beam spot area as possible.
ART-150W & ART-252W User Manual
Check your power cables carefully to ensure that there are no cuts or breach of
integrity of the outer shell at any point. Moisture could be drawn up inside the cable
due to a vacuum generated by heat inside the fixture.
Protect connectors for both power and data lines in a weatherproof housing or a
weatherproof junction box.
If you don't hard wire the fixture to a weatherproof junction box, make sure to use an
IP55 or better rated connector for both plugs and connectors.
Do not connect to a dimmer system.
For your protection, the fixture must be grounded and the AC mains supply must be
outfitted with a circuit breaker and ground-fault protection.
