WiredInternetaccess
MaxemmustbeconnectedtoawiredInternetconnection.Thefollowingisneeded:
• ModemorrouterconnectedtoInternet.
• A DHCP connection from the network to Maxem.
• MaxemshouldbeabletodoDNSrequests.
• MaxemmayalsobeplacedinaDMZ(demilitarizedzone)onaseparateVLAN.

Tesla Wall Connector itself does not measure current, for this a MID kWh-meter is
needed. It can be supplied with Maxem.

Fusing charging station
Maxemisacontrolsystemthatregulatestheloadofthechargingstation.Therefore,itcan
be calculated according to the NEN 1010 with a lower equal time factor*. Maxem makes
surethatthechargingstationislessloadedwhenthereismorechargeinthehouse.The
chargingstationcanthereforebefusedtoavaluehigherthannormal,butnothigherthan
thethresholdvalueofthemainpowersupplyterminal.

230V power supply from Maxem
Maxem measures the power supply as follows:
• Amperage:divisiblecurrentcoilsmeasurethecurrentthroughthephasewires.
• Voltage: internal voltmeter in Maxem with the voltage from the 230V power supply.
For a correct measurement it is necessary to know from which phase Maxem is fed. In
MaxemitisstandardlyinstalledthatthesupplyisonPhase1(L1).

02 - Connecting to power supply

It is advisable to test the network cable with the help of a cable tester.
04 - Connecting charging station
Connect the RS485 cable to the kWh-meter as follows:
• PortC:Greencore
• PortB:Whitecore
• PortA:Browncore
Place the kWh-meter on a DIN-rail in the installation cabinet.
Option 3.2 - Connecting MID kWh-meter to solar panels
Connect the RS485 cable to RS1 port on Maxem.
Connect this in such a way, that it measures the output of the solar inverter.

Option 4.2 - Connecting ICU charging station
Install a circuit breaker or earth leakage circuit breaker for each charging
station at the maximal power available. See p. 10.
Follow the installation instructions of the charging station. These
instructions can be found in the installation manual of the charging
station.

Option 4.3 - Connecting Tesla Wall Connector
Install a circuit breaker or earth leakage circuit breaker for each charging
station at the maximal power available. See p. 10.
Follow the installation instructions of the charging station. These
instructions can be found in the installation manual of the charging
station.
Place a suitable UTP (CAT5 or CAT6) of the Wall Connector to Maxem. (To prevent
electromagneticinterferenceattheRS485connection,itisrecommendedtouseFTP
CAT6cableatdistancemorethan25m.Max:50m).
