3INSTALLATION
3.1 CIVIL WORKS
Each light is usually installed on a suitable concrete block, into which a pipe elbows is
cemented. The isolating transformer is housed into a separate concrete pit which is
normally placed close the above concrete block (Figure 4).
The pit can be placed far from the concrete block too, but in this case a suitable cable
duct has to be provided between the pit and the pipe elbow for passing the
secondary cable.
As alternative the assembly pit-pipe elbow can be replaced by a steel sheet base,
which can be used to house the isolating transformer, complete with an upper steel
plate with a threaded sleeve.

INSTRUCTION MANUAL FOR USE, INSTALLATION AND MAINTENANCE
3.2 INSTALLATION
For the installation of the light the following steps are suggested:
pass together the secondary cable lead with receptacle and a suitable length of
grounding wire (grounded inside the pit) through the pipe elbow
place the receptacle into the upper threaded section of the pipe elbow, by
holding it between the two plastic rings, and pass the grounding wire through the
rings (in correspondence of break point provided on the rings)
open the light, by releasing the clamping spring which secures the lens plate, and
make free the cable leads with plug from the clamping seat
pass the grounding wire through the column and then through the bottom of the
body; pull the grounding wire through the inside of the body and make a suitable
provision of wire
clamp a suitable eyelet terminal (the grounding bolt is M5 threaded) to the wire
but not connect it to the grounding bolt to avoid the wire twisting during the
installation
connect the light plug to the secondary receptacle inside the pipe elbow and be
sure the threaded ring nut is placed close to the top of the column lower
threaded section
screw the column to the pipe elbow; during this operation leave the light open
(eventually supporting by hand the assembly lens plate-lenses) and take care to
avoid the twisting of the grounding wire and the light cable leads
after the screwing completion, lock (not tighten) the column to the pipe elbow by
means of the threaded ring nut, taking care that the arrow of the outer lens is
aimed towards the runway centreline (clamping spring of the lens plate faced to
the runway)
connect the lamp cable leads to the light cable leads with plug and the eyelet
terminal of the grounding wire to the light grounding bolt. Insert the light cable
leads with plug inside the clamping seat to prevent any strain or tugging
place on the light body the levelling-alignment device (P/N 332.3250 available on
request) in fixed position, level the light body by operating the four levelling
screws and then align the light in line with the runway centreline by using the
sights of the device
tighten the threaded ring nut of the slipfitter, taking care to not modify the light
alignment. Torque the ring nut at 45 Nm
remove the levelling-alignment device and close the light, by securing the lens
plate to the body by means of the clamping spring
If provided, mount the daymarker cone on the suitable supporting plate of the
body, by fastening it by means of the four screws.
