•
A correct circuit breaker or earth leakage circuit breaker with proper fusing value.
See
p. 33 to determine fusing.
•
Schuko sockets for 230V power supply Maxem (if not already available).
•
UTP (CAT5 or CAT6) data cable for connecting charging station to Maxem.
•
RJ45 (8P8C) connectors for ethernet connected charging stations (ICU / Keba).
•
Cable end sleeves for UTP cores (only for Tesla Wall Connector).
•
Internet connected smartphone, tablet or computer.

What do I need for the installation?
Wired Internet access
With Maxem compatible charging stations
Compatibility may change over time. See the website www.maxem.io for the current
overview of compatible charging stations.

The following network settings are required. Don’t be alarmed by the jargon, these are
normal network settings. In corporate networks some options can be blocked:
•
Maxem has to receive an IP address via DHCP.
•
This IP address may not be in the following range: 10.50.0.0/16, 10.51.0.0/16, and
192.168.25.1/24.
•
In case of a firewall outgoing traffic has to be allowed on the following ports: 80, 443,
1194 t/m 1200 and 9090.
Fusing charging station
Maxem is a control system that regulates the load of the charging station. Maxem makes
sure that there is less load on the charging station when there is more load on the house.
This reduces the diversity factor. The charging station can therefore be fused to a value
higher than normal, but not higher than the threshold value of the main grid connection.
For more information on this subject in relation to the NEN1010, see the Maxem website.

Current transformers of kWh-meters
Maxem is standard supplied with current transformers with which the main grid connection
and solar production can be measured. For more accurate measurements it is also possible
to use MID certified kWh-meters. The kWh-meters Maxem works with can be ordered
separately.
There are situations when a kWh-meter is always required:
•
Measurement of a Tesla Wall Connector
•
Measurement of a heat pump
