11.7 GUIDE TO HARDWARE INSTALLATION
 Close the jumper TM-C1 if the board is the last element of a CAN bus network
 Connect the signal SHIELD of the connector M1 to the nearest earth point
 Connect the signals CAN_L and CAN_H of the connector M1
 Connect the braiding of the CAN bus cable to earth
 Connect the signal CAN_GND of the connector M1 of all the CAN modules, as the
CAN interface is not isolated. This guarantees that the voltage between tranceivers
never reaches the maximum level
 Install the board in an omega guide
 Supply the module with 18V – 36V DC through the connector M3
