Replacing a 3G Rogowski Auditor with a
4G Rogowski Auditor (A3RM)
Same hardware, better connectivity for the future
Swap out must be done by licensed electricians only!
Make sure your environment is electrically safe and you have isolated all power to the board you are working
on so you can begin to safely swap out the 3G Auditor.
IMPORTANT:
There is no need to physically remove any R-coils or modify any wiring at any stage of the
swap. Remove all power from circuits any Rogowski-coils are attached to before swapping out the device.
STEP 1/7.
Remove the stubby antenna installed to the front of the Auditor. (Turn anti clockwise)
If there is an external high gain antenna installed, you can disconnect it for the swap then reinstate it at the
end
. Leave the provided 4G antenna in the switchboard
in case it ever needs to be used.
STEP 2/7.
Gently remove the green plugs on the top and bottom of the Auditor device. There are no clips on
the green plugs, just a gentle force is required.

look like just before it is removed with power off and
green plugs removed.
STEP 3/7
. Pop out the Auditors DIN rail clips, then remove the 3G Wattwatchers Auditor device. Insert the
new 4G Wattwatchers Auditor device and reconnect both green plugs.
