2 • INSTALLATION AND CONNECTION
This section contains the instructions necessa-
ry for correct installation of the GF_VEDO HL
into the machine control panel or the host
system and for correct connection of the con-
troller power supply, inputs, outputs and inter-
faces.
Before proceeding with installation read
the following warnings carefully!
Remember that lack of observation of these
warnings could lead to problems of electri-
cal safety and electromagnetic compatibili-
ty, as well as invalidating the warranty.
Electrical power supply
• the GF_VEDO ML 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 opera-
tor. 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 machi-
ne structure.
• if the GF_VEDO ML 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 explo-
sive environments; it may be connected to equipment
operating in such atmospheres only by means of appro-
priate 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 ML 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 indicated in
the table below.
BT Conformity (low voltage) in accordance with
Directive 2006/95/CE.
EMC conformity has been tested with the following
connections.
