2 • INSTALLATION AND CONNECTION
This section contains the instructions necessary
for correct installation of the GF_VEDO TL into
the machine control panel or the host system
and for correct connection of the controller
power supply, inputs, outputs and interfaces.
Before proceeding with installation read the
following warnings carefully!
Remember that lack of observation of these
warnings could lead to problems of electrical
safety and electromagnetic compatibility, as
well as invalidating the warranty..
Electrical power supply
• the GF_VEDO TL is NOT equipped with an On/Off
switch: the user must provide a two-phase
disconnecting switch that conforms to the required
safety standards (CE marking), to cut off the power
supply upstream of the terminal.
The switch must be located in the immediate vicinity of
the terminal and must be within easy reach of the
operator.
One switch may control more than one terminal
• if the terminal is connected to NOT isolated electrical
equipment (e.g. thermocouples), the earth connection
must be made with a specific conductor to prevent the
connection itself from coming directly through the
machine structure.
• if the GF_VEDO TL is used in applications with risk of
damage to persons, machinery or materials, it is
essential to connect it up to auxiliary alarm
equipment. It is advisable to make sure that alarm
signals are also triggered during normal operation.
The terminal must NOT be installed in flammable or
explosive environments; it may be connected to
equipment operating in such atmospheres only by
means of appropriate and adequate types of
interface, conforming to the applicable safety
standards.
Notes Concerning Electrical Safety and
Electromagnetic Compatibility:
CE MARKING: EMC Conformity (electromagnetic
compatibility)
in accordance with EEC Directive 2004/108/CE.
GF_VEDO TL series are mainly designed to operate in
industrial environments, installed on the switch boards
or control panels of productive process machines or
plants. As regards electromagnetic compatibility, the
strictest generic standards have been adopted, as indi-
cated in the table below.
BT Conformity (low voltage) in accordance with
Directive 2006/95/CE.
EMC conformity has been tested with the following
connections.
