## Installing the FerIT Node

Refer to the [FerIT documentation](https://rubiconwater.atlassian.net/wiki/spaces/FER/pages/1932689644) for installation instructions

## Connecting the Keller Pressure Sensor

| **Wire Colour** | **Preciseline Function** | **FerIT Pin** |
| --- | --- | --- |
| Red | OUTPUT | NC |
| Black | VCC | Pin 5 “+” (Positive, 12V Out) |
| Blue | RS485A | Pin 6 ”RS485A” |
| Yellow | RS485B | Pin 4 “RS485B” |
| White | GND | Pin 8 “-” (Negative) |
| Drain | CONNECT DRAIN WIRE  
TO A LOW-IMPEDANCE EARTH GROUND |  |

Thread the connecting loom through the mounting arrangement to the FerIT Solar Node mount.  Pass the connecting loom through the base grommet and connect to the M12 8-pin splitter.  Connect the splitter between the FerIT Node and the power module.

## Driver Installation

> ℹ️ Refer to the [https://rubiconwater.atlassian.net/wiki/spaces/DC](https://rubiconwater.atlassian.net/wiki/spaces/DC) documentation for procedures to install and configure drivers

Keller pressure sensor uses the ‘Preciseline' driver in the FerIT device

1. Connect the battery
2. In DeviceConnect, scan for devices. Once found, connect the the FerIT
3. Navigate to the **Drivers** tab and select **Add**, then find and add the 'Preciseline' driver.
4. Enter the access code provided
5. Allow the FerIT to restart and then reconnect

## Driver Configuration

> ⚠️ The settings and data units are dependant on your browser language. Ensure you have selected English (Australia) to display as metric, or English (United States) to display as Imperial

## Inspection Test Plan (ITP):

Download and complete the ITP
