Wallbox eNext Series Installation Manual
This device detects if a contactor is welded and protects the Charge Point.
This protection is performed by sending a signal to a trip coil that trips the electric protections
and Charge Point stops the charge transaction. After that, the Charge Point shows 12 blinking red
lights. In order to solve this error, please contact with technical support.
If protections are placed inside the Charge
Point, no further actions are required to
enable this feature.
If protections are installed outside the
Charge Point, they must include a trip
coil and its signal shall be connected to
the Charge Point as shown on the left.

The DC current leakage detector is an optional device that detects any DC leakage and protects
the facility. This protection is performed in two different ways depending on the Charge Point
power supply.
• Single-phase power supply: The detector sends a signal to the Charge Point main PCB
which stops the charge transaction by opening the inner relays. This error is notified by 6
blinking red lights.
In order to restart the charge transaction, unplug the EV. When the beacon lights turn back
to green and it is possible to start another charge transaction.
• Three-phase power supply: The detector sends a signal to a trip coil that trips the electric
protections. Meanwhile, the Charge Point stops the charge transaction and notifies the
error by 6 bliking red lights.
In order to restart the charge transaction, unplug the EV.
When the EV is unplugged, the Charge Point shows 6 blinking red lights until the current
leak detector is automatically reset. After that, it shows 3 blinking red lights, meaning that
no voltage is detected in the power circuit.
In order to fully restore the Charge Point, rearm the electric protections. The beacon lights
turn back to green and it is possible to start another charge transaction.
