ZJ Beny EV charger review

We recently installed a ZJ Beny three phase charger and took delivery of our electric vehicle (EV). Upon plugging in the charger to the EV, the charging process starts but then stops after about 30 seconds. The accompanying app displays an abnormal error icon and when pressed, shows a message “DLB Wiring Failure” (refer to attached image). We are currently arranging for the installer to investigate the issue, but would like to know if anyone else has experienced a similar problem in the past.
