1 MEASUREMENTS AND INSTALLATION
Measurements in mm (inches). To be fitted on a DIN rail, in a control panel.
To install the device operate as shown in pictures 1 and 2.
To remove the device, first remove any screw-in removable terminal blocks mounted in the
lower part, then operate as shown in pictures 3 and 4.
To install the device again press down the clip before.
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
- The power supplies of the controllers connected to the RS-485 networks must be
galvanically isolated from each other
- to reduce any electromagnetic interference connect the power cables as far away
as possible from the signal cables and, if necessary, connect to RS-485 MODBUS
networks using a twisted pair
- the maximum number of controllers that can be connected to each RS-485 port is
6
- compatibility with the EPoCA® cloud platform of the connected controllers depends
on the type of controller: consult the document "EPoCA - List of compatible control-
lers" available on the website www.evco.it, which can also be accessed by scanning

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
