4. WIRING
The installation must include an interrupting device for the disconnection in all poles. The
minimum distance of disconnected contacts must be at least 3 mm.
Current supply must be protected with a differential residual device intended at most for
the value equal to 30 mA in accordance with the provisions of the standard NFC15-100.
Wiring does not require dismantling of the convector.
The convector must not be installed under a fixed socket.
Use the original flexible cable (3 x 1 or 1.5 mm
2
AO5 VVF) and connect it to the mains
through a terminal box (the brown conductor = a phase, the blue conductor = a zero, the
black conductor = a pilot /measuring/ conductor).
The black conductor is meant for connecting a programming device which programs the
activity of the convector according to the use of a room; when the installation is carried
out with the programming device, this conductor is not used. In such case, it is
recommended to insulate the conductor from any electrical contact through a terminal box
or a domino.
¨
IMPORTANT:
In no case connect the black conductor to an earthing clip or a GREEN-YELLOW
conductor.
If the supply cable is damaged, it must be exchanged by the manufacturer, its after-sale
service or a qualified person to prevent any danger.
Verify that the conductors are tightened
correctly in the terminals of the terminal
box.
Any intervention in the convector must only
be carried out by qualified and approved
persons when the convector is
disconnected from the mains.
If the heating installation is programmed
through the pilot conductor, it is necessary
to disconnect the supply of the respective
convector/convectors and the pilot
conductor/conductors before any
intervention.

NOTE:
- The programming orders are distributed through the following signals
measured with regard to the zero conductor.
-Observe the direction of wiring:
