II. Installation and Connection of Device
All connections should be made when the power is cut off at the circuit breaker. This will
protect against accidental short circuits during installation.
Connect the Device to the tank level sensor before making the connection to the NMEA 2000
network. This will protect against accidental sparks which can be hazardous when working
with fuel tanks.
The Device requires no maintenance. When deciding where to install the Device, choose a dry mounting
location. Despite the fact that the Device’s case is waterproof, its wire terminals are open, and seawater can
cause corrosion or a short circuit. Do not place the Device where it can be flooded by water, get wet in rain
or be sprayed by water.
The Device has two mount holes (see Section I), 4 mm in diameter. Use the supplied screws to fix the Device
on a flat surface. The orientation is not important. However, when the holes of wire terminals are pointing
down, they are better protected from occasional spray.
1. Tank level sensor connection
The Device has four measurement channels (A, B, C, D) which share a common electrical ground (two
Ground wire terminals, labeled as GND, are connected inside and galvanically isolated from the NMEA
2000 ground).
The channel contains two individual inputs: a sensor input (labeled as SENS), which should be connected
to the tank sensor, and a voltage reference input (labeled as VREF), used in parallel connection with analog
gauges.
Different channels may have different connection schemes and settings. In this section, we will show an
example of the possible connections for one channel, and channel name will be omitted on the drawings.
