5.6 CAN1 interface for the CANopen protocol, J1939 protocol, etc.
The CAN1- interface is not electrically isolated.
CAUTION
NON-GALVANICALLY-ISOLATED INTERFACES
The XV300 may be damaged by potential differences.
The GND terminals of all bus modules must be connected.
Do not connect the connector to the XV300 or disconnect it without first de-
energizing the system.
