Power lines should be correctly terminated and insulated and wired up with a fuse somewhere 
between the unit and power source before being connected to a power source. 
 
 
The CAN interface does not include a termination resistor. Appropriate termination must be 
used, e.g. if used in a single device connection, a 120 Ω terminating resistor must be added 
between the CAN+ and CAN- pins.
