SPECIAL CONFIGURATION FOR LONG DISTANCES.
It is recommended the power supply ground cable of
the installation (cable n° 5 in the case of standard
monitors or cable 2M in that of digital monitors) is
connected to terminal block 2/5 (GROUND) of the
distributor in installations in which the distance between
the street panel and the distributor exceeds 500 metres.
Apart from this connection, it is necessary to modify
the internal configuration of the distributor. Open the
distributor and change the internal configuration bridge
to position J2 (default position is J1) to do so. The
