PowerMeter INSTALLATION
Dynamic Power Management (DPM) is a smart function that allows you to recharge your electric
vehicle using only the power available at home, modulating the charging power and avoiding
unpleasant blackouts. If you are using other appliances during the charging session, the system
can modulate the charging power towards the car, even suspending temporarily the charging
session. As soon as the other domestic appliances are switched o, the session will resume at
maximum power.
Do not try to install the PowerMeter if you are not qualied as a professional
electrician. Such behavior can cause serious danger and harm to you and to the
people, things or animals around you.
The wallbox can work without Dynamic Power Management.
In this case, the installation of a dedicated PowerMeter is not necessary, but
avoidance of blackouts is not guaranteed.
Please refer to local regulations and user and wallbox installer manuals on
www.esolutions.free2move.com/document-library/ for more information about
the installation process.
Only PowerMeters provided by Free2move eSolutions S.p.A. are compatible.
Installation must be performed by qualied personnel in accordance with local
regulations.
