06 - Commissioning

Maxem runs during commissioning an autoconfiguration process where all measuring

points, charging stations and other devices are recognized and set. Follow the following

steps:

Put on the charging station or restart it to take off the current temporarily and put it

on again.

Connect the 230V power supply to Maxem or restart Maxem to pull the 230V supply

cable temporarily from the plug and plug it in again.

After successful installation, Maxem sends a current limiting value to the charging

station. In case of non-successful installation, this is not the case. This results in

OVERLOAD OF THE POWER SUPPLY. Cohere should therefore always give OK for a

successful installation.
