 The first option is more aligned with the official N2K method. But, in case of multiple Victron products that need to be connected to the N2K network, will require more wire runs and definitively more NMEA2000 to VE.Can conversion cables.

+==== 3.4 DC Voltage compatibility ====
+The Victron VE.Can network accepts 9 to 70VDC.
+The NMEA-2000 network used to be 9 to 16VDC, which is, or will be, expanded to also include 24V. Which means that some NMEA-2000 devices are 9 to 16VDC, some are 9 to 30VDC, and some allow higher voltages.
+Also, the Victron VE.Can network will (in most cases) be powered with battery voltage. So for a 48V system, the voltage on the VE.Can network **exceeds** the NMEA-2000 accepted voltage levels.
+Therefore, it is important to **not** connect those power cables.
+The Victron cable used to connect both networks together, the [[https://www.victronenergy.com/accessories/ve-can-to-nmea2000-micro-c-male|VE.Can to NMEA 2000 cable]], has a removable fuse which is to be removed in case separation is necessary. A printed warning label is attached to the cable to warn about this.
