9 Step installation guide

All Auditor devices can be used for single-phase, two-phase and three-phase sites. 

Before installing

1. Make sure you have read the safety manual.

2. Make sure you have a multi-meter with a clamp for testing.

3. Make sure the site has a good 4G signal.

3. Make sure all power to the board you are working on is isolated and turned off.

4. Wattwatchers hardware must be installed by a licensed electrician. 

Step 1. Label your CTs

Take out all the CTs and label them on both ends. This is an important step and will help you not only identify each CT, but it will save any future problem-solving if needed. 

Step 2. Place the Auditor inside the switchboard.

Place the Auditor into the switchboard making sure the CTs will reach the desired circuits. If they do not reach, you can extend the CT cables up to 10m.

Step 3. Place the label sticker under the circuit breaker

Inside the box is a small sticker with a QR Code and the serial number under it. Place the sticker under the circuit breaker that will be powering the Auditor.

Step 4. Get your voltage connectors ready

Inside the box, you will have a pre-wired single-phase voltage connector and two separate tails (One white, one blue). 

Make sure the tails can reach the circuit breaker, if not, you can choose to use your own cable to wire the voltage connector. 

a. For single-phase sites

Use the pre-wired single-phase voltage connector and plug it into the top of the Auditor

b.  For multi-phase sites

Remove all the tails from the single-phase voltage connector except the neutral and proceed to wire in the multi-phase tails so the connector looks like the picture below (Multi-phase voltage connector) 

c. For two-phase sites

If you have a two-phase site, you can wire the connector to suit your required monitoring needs. We recommend you contact Wattwatchers to help with two-phase sites so we can help customise your wiring needs to suit the way you are going to monitor the circuits. 

Step 5. Plug in the voltage connector and wire into the breaker

Plug in the Voltage connector and wire your tails into your circuit breaker. The circuit breaker should be no larger than 10A and it is highly preferred if the circuit breaker is dedicated to the Auditor so the customer can power-cycle the device if debugging is ever needed. 

Step 6. Connect your CTs

Connect your CTs to the circuits you are monitoring. Auditor devices that are multi-phase are sensitive to phase positions so you must follow the wiring guides to make sure the CTs are on the correct phase, failure to do so will give incorrect readings.  

See here for a full list of wiring diagrams that you can use (6MW-CER wiring diagrams) or see the most common install diagram below

 

 

Make sure your CTs are facing the correct way!
The direction arrow is clearly printed on each CT. Point the arrow for each CT in the direction as illustrated below.

 

Step 7. Connect your auxiliary equipment where applicable

For more information regarding Modbus connections > See here (Soon to come)

For more information regarding Contactor connections > See here (Soon to come)

Step 8. Turn device on

Once the device has been installed correctly and you are satisfied that the CTs are on the correct phase and the arrows are facing the right way, you can switch the Auditor on when safe to do so. You will need two solid green lights, the ON light (L1) and the cellular connection light (L2). Please wait up to 5 minutes for these to connect.

Quick note regarding communication and signal 

 

Step 8. Commission the device using the Onboarding tool

You will need an onboarding account to commission the Auditor. Contact Wattwatchers Installer Support if you need access.

Onboarding is a simple tool that is used to set up the device and check the live data.

To onboard the device go to wattwatchers.app on your smart device or scan the QR code on the front of the Auditor

To learn how to use Onboarding, you can watch our 6 minute video here which includes a comprehensive guide.
