Section 2: Wiring and Mounting
Warning:
Remove power from all wiring and circuitry before installing or working on the Beacon.
Wiring the Beacon
The Beacon is supplied with a power cable pre-wired to the internal electronics to
facilitate installation. The only connection required is 24-48Vdc power. The ground wire
must be connected for proper operation and protection of the Beacon.
Terminal Wire Color
Negative DC In Black
Positive DC In White
Chassis/Ground Green
Note: For maximum immunity to high RF field strengths, such as might be experienced
on some radio antenna towers, it is recommended that the power cable be shielded. The
shielding should be complete and grounded at both ends. A shielded power cable could
either pass through the strain relief gland on the bottom stem, after removal and cutting
short of the existing cable, or directly into the hole at the bottom of the light. The cables
can be joined inside the hollow stem, from underneath the light.
Mounting the Beacon
Dialight recommends the installation of one or more lightning rods near the installed
Beacon. The lightning rods should extend a minimum of three feet above the height of
the Beacon.
The Beacon is mounted to the tower pedestal utilizing customer supplied ½” hardware.
Six mounting holes are provided on the Beacon base (Figure 2). These mounting holes
will align with most tower pedestals. The Beacon should be installed level to maintain
light output in accordance with FAA requirements.
