The Auditor device has a warning symbol (see on the left) on the side of the Auditor
device which indicates that the device may cause electric shock to a person if the
device is opened, which can result in personal injury or even death. The warranty will
also be voided if the device is opened or otherwise tampered with, without written
authority from Wattwatchers.
To prevent safety risks,, including the potential for injury or death, please use the test
and short-circuit blocks with the billing current transformers (CTs) that are supplied
for the CET PMC meters.
Never connect a billing CT—which has a 5A output—to the Auditor device. Billing CTs
are only designed for connecting to the CET PMC meters.
WARNING: Billing CTs have a potential of 5 AMPS on the secondary side when
connected. If exposed to the open terminal when the CT is operational, there is a risk
of serious injury or death.
The Auditor device must be installed by a licensed electrician, or an individual with
equivalent qualifications as required by the laws of the relevant state or country. The
installer must possess comprehensive knowledge of applicable standards and
directives within the jurisdiction where the device is being installed.
The warranty will be voided if the device is installed by someone who does not meet
the minimum licensing requirements for electrical device installation. The installer
must adhere to this safety guide, as well as the rules, regulations, and laws of the
state/country where the device is being installed. Failure to comply with the safety
guide will also void the warranty. Please read the full safety manual in the link above.
YOU MUST READ THE FULL SAFETY MANUAL BEFORE INSTALLATION!
You must read the full safety manual given to you before installing the 6M+One.
The safety manual contains information and advice on how to avoid damaging the
Auditor device, and how to avoid personal injury or death. You will find a copy of the
safety manual in the link below or by scanning the QR code.

Step 1. Mount the A6M and the PMC Meter
Step 2. Follow the wiring diagrams
Step 3. Watch the Onboarding video
Step 4. Use Onboarding to commission the Auditor
Step 5. Apply the silver stickers
Step 6. Take photos of your installation
STEPS TOWARD A
SUCCESSFUL
INSTALLATION
MAKE SURE YOU HAVE AN ONBOARDING ACCOUNT
Make sure you have access to onboard the device before going to the site. See the
'HOW TO USE ONBOARDING' page for more info.
TAKE SPARE PARTS
Take a spare A6M+One pack if you have one and an external high-gain antenna.
LABEL THE CTS ON BOTH ENDS
Label all the CTs on both ends before you install. This will save a lot of headaches if
you need to retrace any cables for problem-solving.
APPLY THE SILVER STICKER
You will have two silver serial number label stickers. Apply one on the front of the
Auditor (don't block the lights) and one below the circuit breaker feeding it.

Make sure your Onboarding account has access to the device
Please make sure the fleet manager has arranged your access to the device. If you do
not have login access to the device, the fleet manager must request your access to be
set up by Wattwatchers Support. Installers cannot request access directly to support.
Already have an account? Great! But remember to ask the fleet manager if you are
added to their account as an installer so you can onboard their devices.

ONBOARDING
Once you have installed the device
and it's powered up, it's time to
Onboard the device!

The Modbus tab helps you validate the readings
You don't need to pair or add the PMC meter, as it will be automatically
detected once the Modbus cable has been correctly wired to the Modbus
inputs of the A6M.
Power factor (PF) should always be in a positive state and not show a
negative sign. You want to see a good range between 0.8 and 1.0 when
sufficient load is present
0.8–1.0
The Start, Channel and Energy screens are explained in the Onboarding video

NO LIGHTS ON THE AUDITOR
Check for voltage on the device. If voltage is present but all lights are still off, make
sure green plug is seated correctly and power cycle the device.
L3 OFF OR L3 FLASHING
This indicates that the Auditor has poor/no signal. Improve signal by installing a high
gain 4G antenna. Contact Support to see if stock is available.
