Description
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 monitoredand controlledhistorically 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.

Installation requirements
Before you start the installation, check that the following points are fulfilled:
1. you have a smartphone or laptop to activate the CLEMAP product.
2. there is enough space in the fuse box to install the CLEMAP product.
a. Yes → Go to step 3.
b. No → Check whether you can install CLEMAP next to the fuse box.
CLEMAP can also be installed in other fuse boxes. Continue to point 3.
3. Is there an Ethernet cable connection or possibly a WIFI network at the installation
location of the CLEMAP product?
a. Yes → Start the installation.
b. No → Pull a LAN cable up to the CLEMAP sensor or install a WIFI repeater
and continue with the installation.
Safety notice
Power cable colours and their meaning
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).
The following are the colours of the power cables:
Phase
L1, L2 and L3
brown, black, grey
Neutral
N
blue
Earth
PE
green-yellow
However, especially with older installations, do not assume that the colour scheme of the electrical
installation is correct.
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.

FAQ –Frequently asked questions
During installation, the CLEMAP product does not create a WIFI network with the name «clemapXX»:
NOTE: For security reasons, the hotspot is deactivated after 10 minutes without connection. To reactivate it, press
the RESET button for more than 1 second (until the status LED starts flashing rapidly).
If the Edge Device does not find a WLAN network to connect to, it goes into discovery mode and provides its own
WLAN network (called "clemapXX"). It may take up to 3 minutes until "clemapXX" appears among the available
networks.
ATTENTION: If an Ethernet cable is connected to the CLEMAP product, the clemap WLAN hotspot is automatically
deactivated.
The password for clemapXX WIFI network is not accepted:
After entering the clemapXX WIFI network password “sensorsetup”, it is not accepted.
The network is set up, try again in 30 seconds.
I can’t reach floem.clemap.com through my browser:
Check the network connection. Check that you have selected the correct home WIFI and that you can reach the
Internet (e.g. www.google.com). Try again later.
During the installation (step 2) I cannot reach 192.168.1.100:4000 via my browser:
Check whether you are connected to the “clemapXX”WIFI network or whether the LAN cable is plugged in. Refresh
the webpage http://192.168.1.100:4000 and wait up to 30 seconds. Check again that you are connected to the
“clemapXX”WIFI network or that the LAN cable is plugged in and try to access the webpage
http://192.168.1.100:4000 again. If you still cannot access the webpage, try opening the webpage with another
device, e.g. another mobile phone or computer.
Perform a hard reboot by pressing the RESET button for more than 5 seconds (and less than 10 seconds) and wait 3
minutes.
During the installation (step 2) I cannot find my WIFI in the list of available networks:
Check whether the WIFI reaches the control cabinet in which the CLEMAP product is installed. If the WIFI router is
too far away, install a LAN cable, a power line adapter (e.g. TP-LINK TL-WPA4220KIT) or a WIFI repeater. The sensor
only supports WIFI networks on the 2.4 GHz frequency, if the network is on the 5 GHz frequency, activate transmission
on 2.4 GHz via the menu of your WIFI router or install a repeater.
Ground fault circuit interrupter switches off
The RCD can compare the amount of current flowing in and out. If the sum is intact, the current flowing in must be
as high as the current flowing back, whereby the sum of the currents of the neutral conductor and phases must be
zero. If this is not the case, the RCD disconnects the circuit, it "pops out". If L1, L2 and/or L3 are connected after the
RCD and the neutral is connected before it, the RCD will notice a difference between the current flowing back and
forth. Make sure that L1, L2, L3 and the neutral are connected after the RCD.

The sensor cannot connect to the cloud (status LED flashes):
1. Check whether the ports TCP 443, 3032, 8883 and
UDP 123 of the wireless router are open.
2. Perform a hard reboot by pressing the RESET
button for more than 5 seconds (and less than 10
seconds) and wait 3 minutes.
3. Some charging station models have their own DNS
server which may interfere with the setup process.
Plug charging stations into the router last so that
the IP address is given by the router and not by the
charging station.
Figure 16 Hard Reboot
I have installed the CLEMAP product correctly and registered it on the platform,
but the data is not accessible on floem.clemap.com:
Check whether the sensor is communicating with https://floem.clemap.com by looking at the LED status on the
sensor. If this flashes or is switched off, check whether the radio connection is also accessible when the control
cabinet door is closed (install a repeater if necessary) and whether the router doors are open.
→ See question: The sensor cannot connect to the cloud (status LED flashes).
If the status LED is constantly lit, check at https://floem.clemap.com whether the measuring point is online. If this is
not the case, please contact support.
