Installer manual
1 MEASUREMENTS AND INSTALLATION
Measurements in mm (inches); to be fitted on rigid support, with cable tie (not provided).
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.
- The compatibility of the controller with the remote monitoring system EPoCA and
the possibility to power EVlink Wi-Fi from the controller depends on the kind of
controller. Consult the document "EPoCA - List of compatible controllers" available
on the web site www.evco.it and/or the controller label
- If EVlink Wi-Fi must be powered with independent power supply, do not power it
with the same power source of the controller connected to EVlink Wi-Fi
- The battery of EVlink Wi-Fi is charged by the power supply of the device or by the
independent power supply: for correct operation, the battery must be fully charged
at least once a year
- To reduce any electromagnetic interference connect the power cables as far away
as possible from the signal cables and make the RS-485 connection by using a
twisted pair.
2.1 Example of electrical connection to a controller with TTL MODBUS port
In this example the controller is capable of powering the device.
In this example the controller is not capable of powering the device.
2.2 Example of electrical connection to a controller with RS-485 MODBUS port
In this example the controller is capable of powering the device.
In this example the controller is not capable of powering the device.
PRECAUTIONS FOR ELECTRICAL CONNECTION
- 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 connecting it to the
controller
- Disconnect the device from the controller before doing any type of maintenance
- For repairs and for further information, contact the EVCO sales network.

4 FIRST-TIME USE
1. Install following the instructions given in the section MEASUREMENTS AND INSTALLA-
TION.
2. Power up the controller; see the relative instruction sheet.
3. Configure the controller.
Recommended configuration parameters for first-time use.
PAR. DEF. PARAMETER MIN... MAX.
bLE 1 enable EVlink 0 = no 1 = yes
rE0 15 data-logger sampling interval 0... 240 min
rE1 - - - recorded data according to the controller
4. Disconnect the controller from the mains.
5. Connect the MODBUS port of the device to the MODBUS port of the controller as shown
in the section ELECTRICAL CONNECTION.
6. If the device needs independent power supply, power up the device.
7. Power up the controller and an internal test will be run.
The test normally takes a few seconds, when it is finished the LED of the device will
switch off.
8. If the controller shows the label “rtc” flashing, set the date and time.
Do not disconnect the controller from the mains in the two minutes following the setting
of the date and time.
9. Activate the Wi-Fi of a mobile device, localize the network called "Epoca" followed by a
suffix made of 6 number and letters (for example “Epoca279A62”) and connect it to
the mobile device using password “epocawifi”; always verify the password on the label
of the device.

Manuale installatore
1 DIMENSIONI E INSTALLAZIONE
Dimensioni in mm (in); installazione su supporto rigido, con fascetta stringicavo (non in dota-
zione).
AVVERTENZE PER L’INSTALLAZIONE
- accertarsi che le condizioni di lavoro rientrino nei limiti riportati nel capitolo DATI TEC-
NICI
- non installare il dispositivo in prossimità di fonti di calore, di apparecchi con forti ma-
gneti, di luoghi soggetti alla luce solare diretta, pioggia, umidità, polvere eccessiva, vi-
brazioni meccaniche o scosse
- in conformità alle normative sulla sicurezza, la protezione contro eventuali contatti con
le parti elettriche deve essere assicurata mediante una corretta installazione; tutte le
parti che assicurano la protezione devono essere fissate in modo tale da non poter es-
sere rimosse senza l’aiuto di un utensile.
2 COLLEGAMENTO ELETTRICO
ATTENZIONE
- la compatibilità del controllore con il sistema di monitoraggio remoto EPoCA e la
possibilità di alimentare EVlink Wi-Fi dal controllore è subordinata al tipo di control-
lore. Consultare il documento "EPoCA - Elenco dei controllori compatibili" disponibi-
le sul sito www.evco.it e/o l'etichetta del controllore
- se EVlink Wi-Fi deve disporre di alimentazione autonoma, non alimentarlo con la
stessa fonte di alimentazione del controllore collegato a EVlink Wi-Fi
- la batteria di EVlink Wi-Fi viene caricata dall’alimentazione del dispositivo o dall'a-
limentazione autonoma: per il suo corretto funzionamento, la batteria deve essere
caricata completamente almeno una volta all'anno
- per ridurre eventuali disturbi elettromagnetici, collocare i cavi di potenza il più lon-
tano possibile da quelli di segnale ed eseguire il collegamento RS-485 utilizzando
un doppino twistato.
