Mechanical Installation
The mechanical installation is carried out by fixing the device on a wall with two screws, taking
advantage of the two holes with 60 mm. of distance between them. When tools are used close to the
screws holes, particular attention must be used in order not to damage the electronics around.
Once the electrical installation has been completed apply again the front plastic cover to close the
case. Place the plastic front cover on the plastic base paying attention in that the holes for the
indicators located on the front cover will fit in the relevant LEDs on the board, then press slightly until
the four plastic side teeth snap.
Wiring Instructions
For a correct electrical installation of this telephone interface, follow the wiring diagram sketched
below. At terminals 1..6 the changeover (SPDT) contacts of the output relays are available. These
contacts are voltage free and can be used to drive electrical appliances when wired as described in
the diagram. Terminals 7, 8 e 9 are used by the interface as inputs to acquire a state of an external
contact. Terminal 7 is the common and is internally wired to the power supply ground. At these
terminals can be wired any electrical contact as shown in the diagram.
Note:
It is very important to stress that IN1 and IN2 contacts must be voltage free; in other words it
must be only wired to the telephone interface and not to any other electrical
appliance.
The wiring to the telephone line is made with the cable supplied with the device. This cable is
provided with standard telephone plugs at each end. One of the ends must be plugged in the female
connector located on the board inside the interface, meanwhile the other must be plugged in the
telephone socket located in the installation site. In case the available telephone socket in not
compatible with the supplied cable a proper adaptor must be used: these adaptors are usually
distributed in electrical shops. In case the telephone interface requires a different wiring to the
telephone line, it is important to keep in mind that the device must be wired in parallel to the existing
line, therefore in parallel with other phone line machines. It is not mandatory to respect the polarity of
the wires to be connected to the telephone line.
The device is powered with 12Vdc: this is made with the supplied external 230V~/12V power supply
whose connector must be plugged in the connector located on the interface board as shown in the
diagram.
