If there is no base plate, the OL2 may also be secured to the tower by mounting it on a length of ¾” nipple
or conduit and securing to the nipple/conduit to the tower by means of 2 – 3 U-bolts, marker clamps or
beam clamps. The cable is then secured using the 2,3,4 tape method.
MARKER INSTALLATION AND WIRING
Installation and wiring instruction concerning MKR 371 DC / MKR 372 DC IR marker fixtures are supplied with the
marker kit.
LIGHTNING PROTECTION
All Flash Technology equipment is designed to withstand severe transient over-voltages. However, install a
lightning arresting system to prevent eventual damage by lightning. Transient suppressors from line-to-line and
line-to neutral are recommended at the primary power load center.
Confirm the presence of a copper lightning rod. Ensure the rod is approx. 18” away from the L-864 red LED beacon
and 36” above the beacon for proper protection.
SYSTEM WIRING
This manual may not contain all the information about installation wiring required for your installation.
Important!
If installation drawings prepared specifically for your site disagree with information provided in this
manual, the site installation drawings should take precedence. Consult any site-specific installation wiring
diagrams supplied with your equipment.
Flash Technology wiring diagrams define only minimum requirements recommended for satisfactory equipment
operation. It is the responsibility of the installer to comply with all applicable electrical codes.
All installation wiring should have an insulation rating of 600 volts. Wire size for the lights on each wire run is
calculated from the number of lighting fixtures and the length of the wire on that run.
After the beacon wiring has been terminated to the beacon base ensure all cord grips are fully tightened and both
latches are secured to prevent moisture intrusion.
