Network connection requirements
DEFA Balancer supports Wi-Fi (2.4 or 5GHz) and ethernet connections. DEFA Balancer needs to be
connected to the same network as the charging station.
Ethernet: Follow the steps in Installation and setup in order to connect the Ethernet cable.
Wi-Fi: Make sure there is strong and stable Wi-Fi reception available. Connect to the same network as
the DEFA Power charging station. If necessary, make sure the Wi-Fi password is provided prior to
installation. See the commissioning tool for further instructions on how to connect to Wi-Fi.
The owner may configure DEFA Balancer at a later point through the Power Setup app, but it is
recommended to do so during the installation.
Installation and setup
Installation
DANGER Make sure there is no power in the cable during the installation.

or crimped with a ferrule before being installed in terminal blocks.
WARNING When installing the current sensors, connect the sensor leads to DEFA Balancer
before placing sensors on the selected power cables.
i
NOTICE Keep the distance between the current sensors and DEFA Balancer as short as
possible since the length of the sensor leads will affect measuring accuracy.
