Connector Assignment

6.4 Power-over-CAN (CAN-AIR2-PoC only)

 

DANGER

The CAN-AIR/2-PoC must be supplied by a limited current source (see chapter 5.1)!

DANGER
Device of protection class III

The CAN-AIR/2-PoC may only be driven by power supply current circuits, that are 
contact protected. A power supply, that provides a safety extra-low voltage (SELV or 
PELV) according to EN 60950-1, complies with this conditions.

Functional earthing is allowed, but must not conflict with the safety considerations of the 
system.

INFORMATION

The Power-over-CAN functionality is only provided in the CAN-AIR/2-PoC.
