DazeTechnology DazeBox C, Installation Manual

Page: 23 / 73

Transport the charging station manually in order to install it on the wall
suitable for installation.
4.4. Protection and power supply of the charging station
DazeBox can be connected to TT and TN type earthing systems. It may not
be used for IT systems. In a TN system, a circuit feeding a connection point
should not include a PEN conductor.
Some electric vehicles measure the earth resistance and cannot start
charging if a certain threshold is exceeded. Please refer to the technical
documentation of the vehicle. In any case, it is recommended not to exceed
100 Ω for installation. Do not start the wallbox if the measured earth
resistance is higher than the threshold defined in the regulations.
The maximum impedance at the DazeBox installation point must be less
than Zmax=(0.187+j0.117) Ω, |Zmax|=220 mΩ.
The earth connection is provided by the user's installation.
The supply line and protections must be set up before the wallbox is
installed.
