Power Meter 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.
Only Power Meters provided by Free2Move eSolutions S.p.A. are
compatible. Installation must be performed by qualied personnel in
accordance with local regulations.
The wallbox can work without Dynamic Power Management.
In this case, the installation of a dedicated Power Meter is not necessary,
but avoidance of blackouts is not guaranteed.
Please refer to user and installer manuals and local regulations for
more information about installation of the wallbox.
Do not try to install the Power Meter 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.
