These error codes mean that the charger could not switch its internal relay (the power switch) as expected. The charger stops charging to protect itself and the installation. In OCPP this is reported as PowerSwitchFailure.
What to do
Reboot the charger from the web interface or Connect Hub, or ask your charge point operator to reset it from the back office. If the web interface is not reachable, perform a power cycle: switch off the power to the charger at the fuse box, wait a moment and switch it back on. Then start a new charging session.
If the error persists, download the diagnostics of the charger and contact Peblar support or your installer.
