Installation requirements

CLEMAP Load Management is used for dynamic power limitation of two or more electric charging stations in a garage or car park. The power consumption of the entire building is measured and the remaining available power for the charging stations is calculated and communicated in real time. The load management status can be monitored and controlled historically and in real time via the online portal CLEMAP Floem. CLEMAP Load Management can operate in the local network and basically works perfectly even without an internet connection. However, a temporary internet connection is required during the installation phase. It is also recommended to install a permanent internet connection so that the status of the charging stations can be monitored remotely via CLEMAP Floem after commissioning. CLEMAP Load Management is installed in a fuse box and must be connected to the power supply lines between the meter and the building. Usually there are three input lines in a building: the phase conductors (L1=brown, L2=black and L3=grey) and as output the neutral conductor (also called N=blue). The three current sensors must be connected to the three input lines.

Before you start the installation, check that the following points are fulfilled:

Safety notice: For all work with electricity, safety is paramount. The lines of the area where work is being done must be switched off "all poles" before the work. The best way to do this is to switch off the corresponding fuse. But be careful: All-pole means that all conductors, i.e. the phase as well as the neutral conductor, are de-energised. To ensure this, the residual current circuit breaker (FI) should also be switched off. In addition, the cables must be checked to ensure that they are current-free before touching them.

The function of each conductor can be recognised by the respective colour of the power cable in a proper electrical installation. But be careful: Old buildings often have the wrong colouring of the conductors because the standards have changed several times over the years.

Basically, there are three types of electrical cables. First, there is the active conductor, the outer conductor, also called the phase conductor (L) or simply phase. Then there is the neutral conductor (N). And finally there is the protective conductor (PE), also simply called earth (not used when installing the CLEMAP product).

However, especially with older installations, do not assume that the colour scheme of the electrical installation is correct.
