The CAN Bus requires DC power. The voltage range is 9 to 16 volts.
The power may be supplied by one or more of the products on the
Data Bus or from a separate source. Most equipment manufacturers
strongly recommends that at least two independent sources are
used to supply the data bus power.
The CAN Bus is used to supply power to all the items that are
connected on the bus. For items drawing less than one amp, not
having any other power connection, or another path back to ground
the entire power for the item may be pulled from the CAN Bus. This
requires the CAN Bus to have adequate sources of power.

products entering the market and the ability to connect on to the
bus for testing it is sometimes wise to use two harness where
one would suffice. The connection of the two harness can later
be separated so additional tees can be inserted to add another
product or test equipment.
