Connect the Nebolink directly to your boat’s battery bank, which must give it constant 24/7 power of between 8 and 33 volts DC. The power must stay live even when the boat is switched off, so don’t connect it through a switch, breaker, battery isolator or the ignition.
Connect the RED wire to positive (+) and the BLACK wire to negative (−). Ignore any wires other than red and black.
Fit a 3–5 A inline fuse on the red wire, as close to the battery as possible. This is required: it protects your boat’s wiring. The Nebolink also has its own internal self-resetting fuse.
Note: Warranty may be void if the nebolink is not connected to a constant external power supply. More info
