5 Installation
Installation should only be carried out by a skilled, authorised technician.
The following procedures should be carried out before connecting to the power supply, unless indicated
otherwise.
5.1 Opening the package
If the package has no obvious defect (due to dropping or scratches) check the materials it contains with the list
given in the section Contents of the package in the Introduction.
The packaging material is completely recyclable. The installer technician will be responsible for disposing of the
packaging material by recycling or, in any case, according to the current legislation in the country of use.
5.2 Checking the markings
Before proceeding with the installation, check the identification plates to make sure the supplied material
corresponds to the required specifications, as described in the section Identification data.
Never, under any circumstances, make any changes or connections that are not described in this manual: the
use of inappropriate appliances may expose personnel and the system itself to serious safety hazards.
5.3 Switching on and off
Before connecting the power supply:
• Check the identification plates to make sure the supplied material corresponds with the required
specifications, as described in the section Identification data.
• Make sure the keyboard and other parts of the system are closed so that contact with live parts is
impossible.
• The connecting cable for the matrix is only required during configuration if a local power supply is not used.
In this case the connecting cable to the matrix supplies power to the keyboard and is therefore essential.
• The keyboard and other appliances in the system should be placed on a large, solid base.
• The power supply cables should not get in the way of the installer technician when he is carrying out normal
operations.
• Make sure the power outlet and extension cables, if used, are able to support the system power
consumption.
SWITCHING ON: When using the equipped power supply, connect the power supply jack of the switching
power supply to the corresponding connector marked with 12 V
= . The keyboard can also be powered using
the RJ11 connector (Video line) with a connection to matrixes of the type SM42A, SM82A, SM84A, SM164A or
LXRPS42A / LXRPS42TA, LXRPS82A / LXRPS82TA, LXRPS84A, LXRPS164A. In this case, see the section
about connection with the Matrix.
SWITCHING OFF: Remove the power supply Jack from the corresponding connector. If the power is supplied
via a matrix, disconnect the telephone cable from the RJ11 connector for the matrix line.
