Wiring The Nep-2; Power - Navico Network Expansion Port 2 Manual

Power

Before starting the installation, be sure to turn electrical
power off. If power is left on or turned on during the
installation, fire, electrical shock, or other serious injury
may occur. Be sure that the voltage of the power supply
is compatible with the NEP-2 module.
The NEP-2 has a voltage rating of 12 V DC or 24 V DC.
(9 V DC - 32 V DC max range).
The red wire should always be connected to (+) using
a fuse or thermal breaker (5 Amp) to protect the cable.
The NEP-2 is protected by an internal auto resetting
fuse.
The yellow power control wire has to be either:
•
•
If yellow wire is not connected; NEP-2 will be off.
The device applying voltage to the yellow wire must
share a common ground with NEP-2.
The blue wire will not be used, so cap the end of the blue
wire with a wire nut or electrical tape.
