Wi-Fi connectivity.
EVlinking Wi-Fi is a hardware module with Wi-Fi connectivity that can be connected to our
EPoCA compatible controllers to access the functions of the EPoCA cloud platform or those of
other control or data acquisition systems using the MODBUS TCP protocol.
The EVlinking Wi-Fi module can also be connected to third-party devices using the MODBUS
RTU protocol on the RS-485 port to allow integration with client systems.

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.

ELECTRICAL CONNECTION
N.B.
- The compatibility of the controller with the remote monitoring system EPoCA and
the possibility to power EVlinking 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 EVlinking Wi-Fi must be powered with independent power supply, do not power it
with the same power source of the controller connected to EVlinking Wi-Fi
- The battery of EVlinking 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.

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.

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.
