1 MEASUREMENTS AND INSTALLATION | Measurements in mm (inches)
1.1 Models in plastic container for front installation
Front installation on a plastic or metal panel (with elastic holding flaps).
N.B.
The thickness of a metal panel must be between 0.8 and 1.5 mm (1/32 and 1/16 in),
while that for a plastic panel must be between 0.8 and 3.4 mm (1/32 and 1/8 in).
1.2 Models in plastic container installed from behind
Installed from behind a glass or methacrylate panel (with biadhesive) customizing the keys on
the front of the unit.
N.B.
- The thickness of a glass panel must be between 2.0 and 4.0 mm (1/16 and 1/8 in),
while that for a methacrylate panel must be between 2.0 and 3,0 mm (1/16 e 1/8
in)
- The panel and the material used to make screen printing must not contain
conductive substances
- Keep the device and the panel at a temperature between 15 and 38 °C (59 and
100 °F) about an hour before the installation
- Before the installation clean the panel surface in contact with the biadhesive
carefully, making sure the product used to clean is suitable for the panel material
(we recommend using isopropyl alcohol, hydrocarbon solvent in case of greasy
surfaces); keep cleaning with a cloth as long as it results clean and dry after the
use
- During the installation, exert a uniform and constant pressure about 30 s on the
panel surface in contact with the biadhesive; later keep the device and the panel
horizontally about 48 h at a temperature between 15 and 38 °C (59 and 100 °F).
1.3 Open-frame models
To be installed from behind, with threaded studs and membrane keypad.
INSTALLATION PRECAUTIONS
- 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.
2 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.
In model EVJ254N7VXXRXV the EVlink BLE module is integrated.
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
power.
- 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.
3 FIRST-TIME USE
