Connecting the data link
Danger! Lock out power to the entire installation before working on cables and connections.
Warning! Make sure that cable connections are totally protected from water in approved enclosures
such as sealed junction boxes or sealed cable connectors, or moisture may be drawn up the inside
of the cable by the vacuum effect that results from heating and cooling during operation. Follow the
safety precautions and instructions provided by the enclosure supplier.
Warning! If the supplied power cable is unsuitable for any reason, contact your Martin supplier for
replacement. Exterior 400 Image Projector power and data cables may be installed or replaced only
by Martin or its authorized service agents.
The fixture is supplied with a 1.8 meter (5.9 ft.) data cable tail for data connection. The cable contains both
input and output conductors that are identified as follows:
• 1 x shield = data input and output common
• 2 x white wires = data input and output hot (+)
• 1 x green wire = data input cold (-)
• 1 x brown wire = data output cold (-)
To connect a fixture to the data link:
1. Connect the conductors in the fixture’s cable tail to the data circuit respecting the above color code. If
required, install input and output connectors on the data cable respecting the pinouts described in
“Connection pinouts” on page 18. Standard procedure is to use a male connector on a fixture’s cable tail
for data input and a female connector for data through/output. Do not connect the shield conductor to
ground (earth) or allow it to come into contact with a connector shell, as this may cause interference.
2. Check that cable connection enclosures are sealed, check that all installation work is completed, and
carry out appropriate tests and safety checks before applying power.
