Page 12: Connecting Current Transformers
Click the supplied current transformer around the L1 wire of the circuit breaker to the solar inverter (see fig. 2). No other loads may be connected to this circuit breaker. Connect the current transformer to port 4 of Maxem. Repeat these steps for L2 and L3; connect L2 to port 5, connect L3 to port 6. Make sure each current transformer of each phase is connected to the associated port on Maxem. - Page 13 Circuit breaker solar inverter on sub-panel Circuit breakers fuse Circuit breaker solar inverter Home Home Home Grid / Solar Grid / Solar Grid / Solar Home Grid / Solar Main circuit breaker/ main switch Grid connection meter Connection current transformers grid connection Connection current transformers solar panels...

Page 14: Connecting Mid Kwh-Meters
03 - Connecting MID kWh-meter Configuring an MID kWh-meter Maxem can measure different elements through an external MID certified kWh-meter. In order for the auto configuration to function properly, the kWh-meter must be set to the right address. This is done as follows: Location of the ‘addressing’ function in the menu Standard addressing kWh-meter 1 2 3 Number of devices Device type Addressing Addressing multiple elements Node/device Address Node/device Address Grid connection Solar #1 Solar Solar #2 Charging station... - Page 15 Phoenix MID kWh-meter connector as follows: kWh- Wire Phoenix- meter color connector Brown White Green Connect the green Phoenix connector to port RS1 on Maxem. Set the address of the kWh-meter to corresponding node. Connect a 1-phase solar installation which supplies L3 of the main grid connection also to L3 of the kWh-meter. The same goes for L2.

Page 16: Connecting Charging Station
Install a circuit breaker and/or earth leakage circuit breaker for each charging station at the maximal power available. See p. 33. 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). - Page 17 Correct LED indication Top LED is green; the Wall Connector is ready to charge. Incorrect LED indication Top LED is green, center LED blinks red 4x; the Wall Connector is set to Slave, but is not communicating with Maxem.. See installation manual Tesla Wall Connector for more information.

Page 18: Option 4.2 - Connecting Keba Charging Station
Install a circuit breaker and/or earth leakage circuit breaker at the maximal power available. See p. 33. Place a suitable UTP (CAT5 or CAT6) cable from the charging station to Maxem and clench RJ45 connectors on both sides. Connect the UTP cable to the Ethernet port of the charging station and the ETH port of Maxem. - Page 19 Put DSW 1.3 ON to activate smart charging. Set the DIP switches of DSW1 on the maximal available power. And leave the rest of the DIP switches on OFF. Settings on DSW1 Maximal current strength Example 10A 1 of 3-phase DSW 1.6 OFF DSW 1.7 OFF DSW 1.8 OFF See installation manual KEBA P20/P30 for more information Switch off the Keba P20/P30 (the DIP switch settings only become active after a reset of the charging station).
