Eaton XV300 - CAN Interface; CAN1 Wiring and Specifications

5. External connections
5.6 CAN1 interface for protocols CANopen and J1939
5.6 CAN1 interface for protocols CANopen and J1939
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.

l nc: PIN 1, 4, 5, 8 and 9 must not be connected.
l PIN 3 (CAN-GND) and 6 (GND) are internally inter-
connected.
l The power supply of the CAN bus drivers is implemented
internally.
l A power supply for third party devices is not provided on
the CAN connector.
