LED INSET RUNWAY EDGE LIGHT LIRE
INSTRUCTION MANUAL FOR USE, INSTALLATION AND MAINTENANCE
In case of an inset fixture, installed in the taxiway/runway pavement on its shallow
base far from the relevant isolation transformer, it is necessary to provide a
secondary extension between fixture and transformer. To help the installer to
identify the larger socket of the female connector inside the base (when installed),
the base secondary cable leads are identified by a colour code: the grey wire is wired
to the larger socket, the black wire to the other one. In this way it will be easy to
assure the earthing wiring, above described, between the larger socket of the
transformer secondary connector and the larger pin of the fixture plug.
