General information Enelion Energy Guard (EEG) is a device that monitors energy consumption the whole building. Based on the power ordered from the energy supplier and the current consumption measured by Energy Guard, it is possible to obtain information - how much power can be directed for EV charging. Energy Guard can also be used in the chain of charger stations (car parks, shopping center, fleet parking lots), which allows you to use the full potential of the current supplied energy. Current measurement is performed with the use of measuring coils, which simplifies the installation process. We can distinguish, depending on the needs: Transformers, 26 mm hole diameter and maximum input current 100 A, 300 A with 23 mm × 33 mm hole size or 500 A and 1000 A with 36 mm hole diameter. Fig. 1: Enelion Energy Guard Enelion Energy Guard is compatible with the proprietary Enelion Chain communication protocol, enabling communication with the local network of the charger stations. Thanks for that it is possible to enable Enelion DLB function, providing dynamic load balancing. This allows for more effective use of the connection's power for charging vehicles. INFO See User manual to learn more. The manual contains detailed information on the functionality and use of the device. The Enelion Energy Guard comes with a set of measuring coils. The set of EEG includes four current transformers, intended for installation on the supplying power wires to the building, omitting charger stations or on the main connection supplying the entire facility. For each phase fall one current transformer. 4 Fig. 2: Sample measuring coils INFO Measuring coils with 300A and 500A of maximum current are in opening coils version. It is a possibility of individual choice of measuring coils, according to the customer requirements. General information Energy Guard - Assembly manual 04-2023 3. Design indications of the installation 3.1. Recommended power connection WARNING Enelion Energy Guard is adapted to be powered from five or three-wire (with avoiding the PE conductor), in the TN-S and TT type of networks. HINT Energy Guard can work in 3 or 1 phase configuration. This Assembly manual is based on 3-phase version. All connection should be done taking into account the number of phases. The location of the measuring coils should be noticed in the Dealer Tool Box configuration. The device should not be located in a place of high exposure to sunlight, which could cause overheating. Do not install the device near heat sources nor in the locations exposed to high humidity. It is forbidden to install the device in explosion hazard zone. Before installation, make sure that the mounting space inside the switchboard is sufficient for the device. For more information see the Switchboard modification. Devices for communication with charging terminals are supported by the Enelion Chain communication interface. For implementation of it, a wired connection between devices using a CAT 5 or CAT 6 Ethernet cable is required. WARNING The manufacturer accepts no responsibility for any damage resulting from failure to comply with the above-mentioned recommendations. 3.2. Location selection criteria This device is designed to be installed inside of the electrical switchboard, near of the powering cords, on which should be attached the measuring coils. WARNING It is forbidden to install the device in easily accessible locations. INFO It is possible to choose the place of installation of measuring coils. They can be installed on lines feeding the building load [Fig.3] or together with the charging stations lines feeding the building load only [Fig.4]. 5 Design indications of the installation Energy Guard - Assembly manual 04-2023 L1, L2, L3 N PE Main fuses N L3 L2 L1 P1 S1 P2 S2 P1 S1 P1 S1 P2 S2 P2 S2 CANL CANH Energy Guard Measuring coils 12345 6 Voltage lines 1234 CAN Bus wires, 2 wires, twisted, shielded Charge point fuses other circuts fuses other circuts Enelion charge point CANL CANH Fig. 3: Measurement of the entire connection with the charging terminals. 6 Design indications of the installation Energy Guard - Assembly manual 04-2023 L1, L2, L3 N PE Main fuses CANL CANH Energy Guard Measuring coils 12345 6 Voltage lines 1234 N L3 L2 L1 P1 S1 P2 S2 P1 S1 P1 S1 P2 S2 P2 S2 CAN Bus wires 2 wires, twisted, shielded Charge point fuses other circuts fuses other circuts Enelion charge point CANL CANH Fig. 4: Measurement of the load excluding charging terminals. 7 Design indications of the installation Energy Guard - Assembly manual 4. Assembly WARNING Before commencing the installation, switch off the power supplied to the cables. 04-2023 1. Cables should be prepared and connected to the CAN bus in accordance to the diagram above. The order of the wires does not matter. We suggest using a twisted pair cable with a maximum length of 500 m. INFO Pay attention to communication bus termiantion, both in Energy Guard and charging station. Use termination for devices at the beginning and end of the network. Termination is done by moving the switch in the green connector direction. Termination in enabled by default. [Fig.6]. Fig. 6: Termination switch. Fig. 5: Energy Guard 3-phase variant connection diagram. INFO In case of 1-phase version, only one measuring coil should be connected and belonging to it voltage line. 2. Measuring coils should be installed on wires of all phases according with the order indicated above. WARNING Red arrows show the direction of the current flow. Wrong order or incorrect installation of the current transformers will prevent the properly operation of the EEG. 4.1. Mounting the device Enelion Energy Guard is designed for mounting on a DIN rail, inside the switchboard. 8 Direction of the installation, according to the arrow on the transformer (disconnect the power supply cables to the switchboard and insert through the transformer from the side marked with the arrow). Assembly Energy Guard - Assembly manual INFO Transformers are not equipped with wires. Suggested cables with a conductor crosssection of 0.5 mm2. In the case of custom-made transformers, it is possible to equip them with the necessary wires and connectors to be plugged into the EEG. 04-2023 4.2. Modification of the electrical switchboard Since the Enelion Energy Guard has different dimensions than the standard fuse which is installed in the switchboard, it is required to enlarge the hole in the blend. 3. Voltage lines (power supply) EEG should be connected under the order indicated in the diagram [Fig.5]. The device does not require additional protection. The cables on the switchboard side should be connected to the terminals of the apparatus located before branching the circuits in the switchboard (e.g. a meter or the main protection - overcurrent switch). We suggest using stranded type cables with a core cross-section of 0,5 mm2. WARNING A reliable and stable voltage source must be provided. Connecting the Energy Guard voltage lines to a point constituting a side branch of the installation may result the loss of the power source in the case that this branch would be disconnected, for example by triggering its protection. Fig. 8: EEG installed in the electrical switchboard. INFO It is permissible to mount the EEG in other orientations than directly on the DIN rail, if required by the switchboard design. 4.3. Controll after commissioning After connecting the wiring and mounting the EEG, the power can be restored. The EEG has a very simple interface: Fig. 7: Sample connection of the voltage lines to the selected apparatus in the switchboard. Fig. 9: LED interface on the front of the device.

DLB system Dynamic Load Balancing - DLB - is a smart system of load management used during EV charging process. It allows dividing the total input power between connectors in a way, that allows maintaining consumption below a given level. It helps to prevent surcharging network of the charger's operator with extra fees from an electric power supplier. DLB also allows using available power, which appears after disconnecting any car from the charger in the network. It can be used from the quantity of just two connectors, up to couple of hundreds of them, so it can be applied as well as in the single household as well as in the whole parking lot. power exceeding that available - having 22kW available for chargers, we can have several 22kW chargers that will always charge with the maximum available power. Fig. 10: No DLB system In the basic version, an internet connection is not necessary for DLB to work. After energizing chargers, they'll know what to do. Nevertheless, after fitting ,,master" unit in the Bridge communication module and Enelion administration system, you gain access to many developed functions allowing remote management of charging.

Queuing measurement of the entire connection inclu- ding charging stations [Fig. 3]. According to the IEC 61296 standard, the charger must not limit the car charging current below 6 A per phase (1,4 kW single-phase or 4,1 kW three-phase charging). If there is not enough power, the charger goes into standby mode. Charging will resume when minimum charging power is available again. 2. ,,Power equipment without charging network", i.e. measurement of the connection without charging stations [Fig. 4]. INFO If the suspension occurs while charging more than one car, the charging suspension is queued. The car that has charged the most energy during that charging session will pause first. If necessary, the next cars with the highest energy consumption will be turned off one by one. In a situation where, during the pause, another car gets a higher state of charge than the paused car, the switch will occur. First, the charging car will pause, allowing the second car to resume charging. Information on the connection variants with diagrams can be found in the chapter Design indications of the installation. By default, the chargers will treat the measurement as if they did not include chargers, but it is possible to configure the device using the Delaer Toolbox. INFO Queuing is to evenly distribute energy among all charged cars. 5.5. Maintenance WARNING Incorrect configuration may lead to unexpected behavior of the charging power sharing algorithm. Configuration parameters Current limitation of the mains connection 32 A Comment Corresponds to the limitation per phase - for a singlephase 7,4 kW and threephase installation 22 kW the limitation value will be the same and will be 32 A The device is designed to operate in temperatures from -25 °C do 55 °C.
