MEASUREMENTS AND INSTALLATION
Measurements in mm (inches). To be fitted to a panel, snap-in brackets provided.
INSTALLATION PRECAUTIONS
-
The thickness of the panel must be between 0.8 and 2.0 mm (1/32 and 1/16 in)
-
Ensure that the working conditions are within the limits stated in the TECHNICAL
SPECIFICATIONS section.
-
Do not install the device close to heat sources, equipment with a strong magnetic field,
in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations
or shocks.
-
In compliance with safety regulations, the device must be installed properly to ensure
adequate protection from contact with electrical parts. All protective parts must be
fixed in such a way as to need the aid of a tool to remove them.

ELECTRICAL CONNECTION
N.B.
-
Use cables of an adequate section for the current running through them.
-
To reduce any electromagnetic interference connect the power cables as far away
as possible from the signal cables.
PRECAUTIONS FOR ELECTRICAL CONNECTION
-
If using an electrical or pneumatic screwdriver, adjust the tightening torque.
-
If the device has been moved from a cold to a warm place, the humidity may have
caused condensation to form inside. Wait about an hour before switching on the pow-
er.
-
Make sure that the supply voltage, electrical frequency and power are within the set
limits. See the section TECHNICAL SPECIFICATIONS.
-
Disconnect the power supply before doing any type of maintenance.
-
Do not use the device as safety device.
-
For repairs and for further information, contact the EVCO sales network.
