Installation
LED obstruction lights of different models and/or manufacturers may draw differing
amounts of power. This may make monitoring by measuring operating current difficult
especially when multiple obstruction lights are operated on a single circuit as is common
practice. It is recommended that models/manufacturers not be mixed on a single
installation. The following section describes how to install the LED obstruction light.
Unpacking your LED Obstruction Light
Please examine the shipping containers and their content thoroughly upon receipt and
report any potential shipping damage to the carrier.
Tools for Installation
The following tools are suggested for mounting of the MKR-LTG obstruction lights.
Digital multi-meter capable of reading 600VAC/DC (Fluke 177 or 179)
Nut Drivers and Sockets
#2 Phillips Screwdriver
5/16 Flat Head screwdriver
Crimp Tool
Needle Nose Pliers
Quick Installation
The MKR-LTG1-0IR L-810(L) LED Single Obstruction Light has ¾” NPT side and bottom
hubs available for mounting. The MKR-LTG2-0IR LED Double Obstruction Light has a ¾”
NPT bottom hub available for mounting.
All fixtures, enclosures and junction boxes must be mounted in the upright position.
Leveling
The L-810(L) must be leveled during installation for correct vertical bean alignment.
The following diagrams detail how to use a compact “torpedo” level on two axes to ensure
that the obstruction light is level mounted level. Remove the globe and power supply and
place the level across the base as shown. Adjust fixture as necessary for level
installation.
