Attention: make sure that the earth connection is
efficient. A non-existent or inefficient earth con-
nection can make the operation of the device
unstable, due to excessive environmental.
In particular, check that:
• the voltage between ground and earth is < 1 V;
• the ohm resistance is < 6 Ω.
CAN
Connect the cable for the CAN field bus (CANopen protocol).
The CAN bus connects the various CAN devices, such as
the CAN-IO modules, to the Integrated Controller and / or
Operator Panel.
Considering that the CAN port is opto-isolated, it is not ne-
cessary to disconnect the power to the device before con-
necting it.
For the wiring of the line, use an approved cable.
Fasten the cable connector to that of the controller with the
appropriate screws.

Figure 12 - CAN bus line termination
The line termination is not fitted in the controller.
It is therefore necessary to fit two terminations
(resistor 120 Ω, ¼ W, 5%) at the ends of the CAN
bus, as shown in figure 12.
Note: If the last device of the CAN bus is a CAN-IO module,
it is possible to activate the termination in the module with
the appropriate switches (see the CAN-IO documentation).
Ethernet
If necessary, connect the Ethernet cable to the Ethernet
RJ45 port.
The Ethernet port allows connection of the Integrated Con-
troller and Panel to a computer or to a company LAN net-
work.
The connection cable to use (either straight or crossover)
depends on the type of device that has to be connected.
For example, to directly connect a PC it is necessary to use
a crossover cable.

Straight cable
Figure 13 - straight and crossover Ethernet cables
For the connection, use a CAT6 UTP cable or superior.
The maximum length of the Ethernet cable is 100 metres.
Do not run the Ethernet cable alongside the machine power
cables, to avoid interference with data transmission.
The RJ45 socket has two LEDs. When the Ethernet connec-
tion is active, the green LED stays permanently lit; when data
is being transmitted, the yellow LED flashes.
