6.9 Connection of the power
supply line
CAUTION! The type of cable used must be
compatible with the planned use. Comply
with the national regulations in force on
electrical installation.
Connect the safety earth to the relative
terminal of the power supply connector.
Earth cable should be about 10mm longer
than the other two, so that it will not be
disconnected accidentally if pulled.
Insert the cables inside the housing using the cable
glands. The cable glands are suitable for conductors
with diameters of between 5mm and 10mm. The
section of the cable inside the housing must be
sufficiently long to allow connection. Suitably lock
the cable glands.
Connect the conductors to the terminal (board power
supply, 6.8 Board description, page 11).
