The maximum length of the connection cables to the user interface depends on the CAN port baud-
rate .
Local CAN port:
-
10 m with 20.000 baud
- 5 m with 50.000 baud
- 2 m with 125.000 baud
- 1 m with 500.000 baud.
Wide CAN port:
-
1.000 m with 20.000 baud
- 500 m with 50.000 baud
- 250 m with 125.000 baud
- 50 m with 500.000 baud.
The LocalCAN port baud rate is settable by jumpers (see section wiring layout).
The WideCAN port baud rate is settable by parameter.
Connection with a remote expansion (or another CAN controller) :
The connection between C-PRO GIGA and the remote expansion (or another CAN controller) has
to be done with 4 wire cable (better with two weaved couples).
The maximum length of the connection cables to the remote controllers or expansions depends on
the CAN port baud rate (see above section “User interface connections”)
C-PRO GIGA and the expansion (or other CAN controller) power supply have to be
electrically insulated one from the other.
Electrical wiring cautions
-
do not work with electric or pneumatic screw-wrenches on the connectors of the controller
- if the device has been moved from a cold to a warm environment, humidity condensation
may have formed inside; please, wait approximately one hour before to switching it on.
- ensure that the voltage, frequency and operational power of the device are compatible with
the local power supply
- disconnect the power supply before proceeding with any kind of operation of maintenance
- do not use the device as a safety device
- for repairs and any information relating to the device, contact the Evco dealer network.
Cautions
Besides the maximum length of the connection cables, some other cautions have to be respected :
To avoid immunity problems, it is good practice to observe the following instructions:
- Avoid locations with antennas
- Do not wire probe inputs together with relay outputs; generally avoid combining low and
high voltage
- Avoid winding the wirings onto power components
To avoid safety problems, it is good practice to observe the following instructions:
- Avoid rooms with relative humidity >90%
- Avoid water
- Avoid corrosive environments
- Avoid explosive environments
Besides, ensure that the operating conditions correspond with the use limits indicated in the
technical features.
