Installation of ground screws in a 8” base Image examples
When a base (and/or a light fixture) is to be grounded to earth, the
install of ground screws (supplied separately) in the base is needed:
1.
Install an internal ground screw (G).
From the inside of the base, fasten the self-drilling and
threading screw in the specific countersink marked with
ground symbol.
2.
Install an external ground screw (G).
From the outside of the base, fasten the self-drilling and
threading screw in one of the two possible specific
countersinks (see position in the figure to the right).
4.4 Installing the base
The following installation procedure provides step-by-step instructions for a single base fixing. However, it is recommended
to install several bases at the same time as some steps (such as fixing compound spreading) are carried out more effectively
on a multi-base installation.
4.4.1 Positioning and alignment of a base
When installing bases, an alignment device is needed in order to position and fixate the base in the ground. Depending on
base model, size, function and installation requirements different models of alignment devices are needed.
When installing bases on runways according to ICAO (Annex 14 Volume 1, Aerodrome Design and Operations, 6th edition,
July 2013, Appendix 2), an alignment tool with horizontal adjustment is needed. If positioning jig for 8”-bases is used, note
that the applicable version is the one produced year 2014 or later. When installing bases on taxiways, horizontal adjustment is
not required.
For easier and more accurate base installation when using Positioning jig for 8”/12”-bases, an optional tool called Sight
Telescope can be used. Instructions for how to use the Positioning jig and the Sight Telescope can be found later on in this
chapter.
