The maximum length of the connection cables to the remote user interface depends of 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 an other CAN controller) :
The connection between C-PRO MEGA and the remote expansion (or other CAN controller) has to be done
with 4 wire cable (better if it is two weaved couples).
The maximum length of the connection cables to the remote controllers or expansions depend on the CAN port
baud rate (see above section “User interface connections”)
C-PRO MEGA and the expansion ( or other CAN controller) power supplies has to be electrically
insulated one from the other.
Electrical wiring precautions
-
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.
