Network power supply
The H5000 network requires its own 12 V DC power supply protected
by a 5 amp fuse or breaker. For 24 V systems, use a DC-DC converter
to supply 12 V
Connect power at any location along the backbone for smaller
systems.
For larger systems introduce power at central point in the backbone
to balance the voltage drop of the network.
 Note:
If joining to an existing Micro-C CAN bus backbone or similar
CAN bus network that already has its own power supply, do not
make another power connection.
 Note:
Do not connect the Micro-C CAN bus power cable to the same
battery as the start batteries, autopilot computer, radar, thruster or
other high current devices.
The drawing below demonstrates a typical small network.
