Safety Precautions Before Installation

It is not safe to work on a constant current power system when the power is on. Make sure the power is off before
installing a light fixture. A Lock Out Tag Out procedure is strongly recommended. An additional safety measure
is to test circuit by using a clamp on current meter. By clamping over the primary cable in the fixture can, the
installer has performed an additional safety check by checking the circuit they are working on is off. At the vault
make sure the Constant Current Regulator powering the circuit is off and has been tagged out. At the fixture,
place a clamp-on ammeter over the primary cable and verify that the current measures zero amps.

 

Tool Required

7/16 Wrench

1 1/2 Wrench

T20 Torx Driver for later maintenance 

Electrical Connections

Connect the secondary leads from the isolation transformer to the fixture input using L-823 style connectors.
Select the appropriate isolation transformer: 30/45W without arctic kit; 65W with arctic kit.
Seal all connections per FAA requirements.

Install Fixture

Loosely install the column to the fixture and pass the secondary cable thru the column and frangible coupling.
Connect the secondary to the transformer. Fasten the column to the frangible coupling with a torque of 64 inchpounds
(5.3 foot-pounds).

Install Frangible Coupling

Install frangible coupling into baseplate and torque to 50 ft-lbs. (68Nm). For a 62-1060 coupling into a 2in
NPS baseplate, connect the 62-1060 to a 2in to 1 1/2in reducer, then install the reducer and coupling into the
baseplate with a torque of 50 ft-lbs. (68Nm).

Aim Fixture

The arrows on the fixture cap should be pointed towards the runway centerline. The shorter cross on top of the
cap is used to sight the fixture for alignment with the row of edge lights, the longer member of the cross can be
used to align with the threshold lights.

 

Level Fixture

Place a level on top of the cap and level the fixture. If a torpedo level is used, level in both directions of the cross.
A bull’s eye level can be used at the cross intersection.

Torque Bolts

Once the fixture has been aimed and leveled, torque the ¼-20 fasteners to 64 inch-pounds (5.3 foot-pounds).
Recheck the level of the fixture.

Arctic Kit Installation Note

If arctic kit option (code 5) is present, connect heater wiring per the specific diagram.
Use 65W isolation transformer.
