Solution
1 Reboot the charge point by turning it off by flipping the circuit breaker in the
consumer unit (fuse box) and turn it back on after 20 seconds. It takes around
5-10 minutes for the charge point to reboot.
If no result, proceed to the next step.
2 Is the charge point installed vertically? There is a tilt sensor inside the charge
point that detects if the charge point is not vertical which will activate a safety
mechanism preventing any charge session from starting.
If the charge point is installed vertically, proceed to the next step.
3 Measure the voltage at the grid connection between each phase and neutral.
The voltage range should be within 230 Volt ± 10% (between 207 Volt and 253
Volt). If it is outside this range at the side of the customer's grid connection,
inform the local grid operator about this issue. The grid operator is responsible to
provide a voltage within this range.
If the voltage at the grid connection is within the 10% tolerance, proceed to the next
step.
4 Measure the voltage at the charge point between each phase and neutral. The
voltage range should be within 230 Volt ± 10% (between 207 Volt and 253 Volt). If
it is outside this range at the side of the charge point but within this range at the
grid connection, the cross section of the power cable is large enough (max. 10
mm2).
If the voltage is within the 10% tolerance, proceed to the next step.
5 Measure the earth resistance of the charge point, it should be lower than 100
Ohms. If it is higher, install a proper grounding solution. For example: add an
earthing rod directly connected to the charge point.
If no result:
- Charge point may be broken, please contact your local NewMotion Installation
desk.
