This section contains the instructions necessary
for correct installation of the 1200/1300
controllers 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 controller 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 controller.
The switch must be located in the immediate vicinity of
the controller and must be within easy reach of the
operator. One switch may control more than one
controller.
• if the controller is connected to NOT isolated electri-
cal
equipment (e.g. thermocouples), the earth
connection
must be made with a specific conductor
to prevent the connection itself from coming directly

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 controller 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:
The instrument conforms to the European Directives
2004/108/CE and 2006/95/CE with reference to the
generic standards: EN 61000-6-2 (immunity in industrial
environment) EN 61000-6-3 (emission in residential envi-
ronment) EN 61010-1 (safety).
Series 1200/1300 temperature controllers are mainly
designed to operate in industrial environments, installed
on the switchboards 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.
EMC conformity has been tested with the following
connections.
