Connection with a remote expansion (or an other CAN controller) :
The connection between C-PRO NANO and the remote expansion (or other CAN controller) is made using a 2
way cable (better if weaved) plus possible ground.
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 NANO and the expansion ( or other CAN controller) power supplies has to be electrically
insulated one from the other.
Notes on the electrical connections
-
do not use electric or pneumatic screw-wrenches on the terminal board
- if the device has been moved from a cold to a warm environment, condensation may have formed
inside; please wait approx. one hour prior to switching on
- ensure that the voltage, frequency and operational power of the device are compatible with the local
power supply
- disconnect the power prior to proceeding with any kind of maintenance operation
- do not use the device as a safety device
- for repairs and any information relating to the device, contact the Evco dealer network.
Caution
The instructions governing maximum connecting cable lengths imply that a range of precautions are being
observed:
In order to avoid exemption problems, it is good practice to comply with the following instructions:
- Avoid locations with antennae
- Avoid cabling probe inputs and relay outputs together; generally avoid mixing low and high voltage
signals
- Avoid wrapping cabling around power components
In order to avoid safety problems, it is good practice to comply with the following instructions:
- Avoid premises with relative humidity >90%
- Avoid water
- Avoid corrosive environments
- Avoid explosive environments
Special recommendations
Finally, ensure that the operating conditions are within the limits of use described in the technical
characteristics.
