If there is no error code:
• Check the charger, charging cable and connector for any visible damage.
• Make sure the power LED on the charger is on.
• Make sure that the charging cable is properly inserted and locked into the vehicle.
If you cannot find the reason why your charger is not working properly, please contact your
local reseller or Ratio EV Charging.
Points of attention if the app shows incorrect values while the charger is in Smart (Solar)
mode:
• Make sure the arrows on the current transformers point towards the entry point of the
main power grid.
• Make sure the current transformers L1, L2 and L3 are connected according to the phase
sequence (Sine).
• If the charger indicates deviating values, it can help to switch the CT terminals on L2 and
L3 on the Sensor Box.
• The mains input cable of the Sensor Box must be plugged into a power socket connected
to the same phase as L1 of the charger.
113 PEN Fault detected. Switch off the supply to the charger and
