Installation 11
Installation and User manual
1. Connect the mains power supply to the terminals on the power-supply
module ([A],table 1, K).
For a safety standards compliant system, the Line must be connected to terminal
“L” and the Neutral conductor to terminal “N”.
The power supply must come directly from an electrical distribution panel via a
reserved line. This line must be protected by a suitable sectioning device as
required by the local standards and laws in force.
Note
The electrical system of the building must have a magneto-thermal switch as an
additional protection against overcurrents and short circuits.
The end of a stranded wire must not be consolidated with soft soldering in points
where the wire is subjected to contact pressure.
2. Crimp the earth line wire to the eyelet terminal [B].
3. Secure the wire with the eyelet to the control panel using the ground con-
nection screw [C].
4. Ensure that the terminal “ ” of the power supply module [D]], the main
board [E] and the frontplate [F] are connected to Ground.
ATTENTION!
The earthing system must comply with current regulations regarding electrical
safety in the systems.
A protective earth connection ensures that all exposed conductive surfaces are at
the same electrical potential as the earth surface, in order to avoid the risk of
electrical shock when a person touches a device in which an insulation fault has
occurred. In the event of an insulation fault, a protective earth connection will
generate a high fault current which in turn will trigger an overcurrent protection
device (fuse) and disconnect the power supply.
5. Ensure that low-current safety or signal lines DO NOT come into contact
with points with potentially dangerous currents.
Using a plastic cable tie, bunch the wires together and secure them to one
of the wire hooks on the backplate of the enclosure [G].
The connection wires (to the mains supply and also any other wires inside the
cabinet) must be secured to the cable hooks on the backplate by means of plastic
cable ties. Use cable with double isolation for the connection to the electrical
mains.
