14.1.2. Update device firmware
This menu is visible if a firmware update is available.
We recommend that you update the firmware to ensure that the charger works properly.
14.1.4. Connected phases
Select the phase the charger is connected to.
14.1.3. Maximum charging current
The setting of the maximum charging current must comply with the system di
-
mensioning.
If the electric system dimensioning on the installation site requires a lower charging current
than the charger’s nominal value, you can change the setting in this menu.
14.1.5. Phase rotation (only 3-phase chargers)
Selection of phase rotation is only informative and does not affect the charger operation.
14.1.6. Eathing System
The default setting for power supply is TN network. If you connect the charger to an IT net-
work, you have to change settings for the charger accordingly.
14.1.7. Overcurrent limit
•
Certain car models tend to take more charging current than set as the charger’s maxi-
mum charging current.
•
In case an overcurrent of 10% lasts longer than 3 minutes, it results an error state. If the
overcurrent is 16% it results an error state immediately.
•
You can prevent unnecessary error states by setting an overcurrent limit.
•
If the charging current is lower than 10A, you can set the overcurrent limit up to 30%.
