Fig 7. Apply pressure on the sides of each individual hinge
to remove it from its seat and completely remove the front
panel.
Fig 9. Using the supplied drilling layout, make the four
fixing holes on the wall.
Fig 11. Now make the electrical connections as indicated
in the following chapter.
• For electrical connections, refer to the specific wiring diagram and to the technical characteristics of
the panel model to be installed.
• The power supply to the panel must be carried out exclusively with a dedicated line, upstream
of which a device suitable for protection against indirect contacts (differential switch) must be
installed.
• Avoid putting power cables and signal cables (probes and digital inputs) in the same conduits (or
pipes).
• Avoid using multipolar cables in which there are conductors connected to inductive and power
loads and signal conductors such as probes and digital inputs.
• Reduce the lengths of the connecting cables as much as possible, preventing the wiring from taking
the spiral shape that is harmful to possible inductive effects on the electronics.
• If it's necessary to extend the probes, conductors must be used with a suitable section and in any
case not less than 1 mm2.
Fig 8. Using a screwdriver, press the four pre-set holes on
the back to make the four fixing holes of the electrical
panel.
Fig 10. Using the four holes made previously, fix the
back of the box using four screws of adequate length in
relation to the thickness of the wall. Place a rubber washer
(supplied) between each fastening screw and the back of
the box.
