TN network
TN is the most common grid type in Europe. It uses five
conductors to provide both 230 V and 400 V. This makes
it very efficient and thus the preferred grid type for
charging electric vehicles.
IT/TT network
IT and TT grid systems are mostly used in Norway and
Albania, but occur in Belgium, France and Spain too.
These systems have no neutral connector and use 4
conductors only. They can thus only provide 230 V.
NOTICE! It's recommended to follow the existing colour
codes used in the installation. Depending on national
standards, the colours of the cables can vary from the
illustrations. The illustrations in this manual follow the
IEC 60446 standard.
NOTICE! Make sure the conductors are properly
connected before turning on the power for the Charging
Robot(s).
