INSTALLATION
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.
