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 off, the session will
resume at maximum power.
Do not try to install the PowerMeter if you are not qualified 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.
