Control device classification: Independent mounting, with characteristic of automatic
operation action Type 1.B, to be used in clean situation, logical medium (software) class A.
Double insulation between the power supply, the secondary circuit and the relay output.
The controller must be installed in a place protected from vibrations, water and corrosive
gases, and where the ambient temperature does not surpass the value specified in the
technical data.
In order the controllers be suitable having IP65 protection, the gasket should be installed
properly between the apparatus and the perimeter of the panel cut-out where it is to be
fitted.
In order to give a correct reading, the probe has to be installed in a place without heat
influences other than the temperature that is to be measured or controlled.
Fastening
To fix the unit, place the fasteners 1 over the sliders 2 as shown in
the figure. Move the fasteners in the direction of the arrow. By
pressing tab 3 the fasteners may be moved in the opposite direction
of the arrow.
Connection
See diagram in the unit rating plate.
The probe and its lead should
NEVER
be
installed in ducting along with power,
control or power supply wiring.
The power supply circuit should be
connected with a minimum 2A, 230V, switch located close to the unit. The cables should be of
