7.5 Installation steps CAUTION! Installation and servicing may only be performed by qualified personnel. Opening the HV APU voids the warranty. Improper use or incorrect configuration may damage the HV APU. Step View Designation 1 Position the battery cabinet in the installation location, taking into account the requirements listed under point 5 Open the door of the battery cabinet using the included control cabinet key, which can be found on the outside of the door. 3 Connect the two separate TS 40 battery cabinet with the baying connector (cabinet connector) provided 4 CAUTION! Ensure that the battery cabinet is correctly earthed. Connect the earth to the battery cabinet at one of the earthing bolts provided. 5 CAUTION! Ensure that the HV APU is correctly earthed. Mount the HV APU on the upper slide rail and arrange the included cage nuts in the 19 mounting frame, then use the screws provided to fix the HV APU in place at the four fastening points. Note that earthing at the HV APU is absolutely essential. An earthing bolt is attached at the rear of the HV APU. Attach this to any suitable earthing bolt at the battery cabinet using the potential equalisation cable supplied. The two-pin plug for the e-stop connection to the HV APU must be plugged in upon delivery. Until this is plugged in, the HV APU remains inactive. Further information on the e-stop can be found under point 7.6 of this Installation Manual. >> 14/33

Step View Designation 6 Mount the battery modules in the slide rails provided and measure their voltage. The DC voltage of undamaged battery modules is approx 50 V. Arrange the included cage nuts in the 19 assembly frame, then use the screws provided to fix the HV APU in place at the four fastening points. Start from the top and work towards the bottom. 7 A cable support rail is included with the cabinets to aid tidy cable laying. The cables (DC connecting cables, rack balancing, BAT COM) can be fastened carefully to this rail using cable ties. ATTENTION! Improper connection of the battery damages the battery and the HV APU. Ensure that connection is carried out properly in accordance with the diagram of connections from chapter 7.5. 8 Contact the DC module connector, always bearing in mind that there is a serial battery module connection in the high-voltage variant. It is essential here that the colours of the plugs match the colours of the device parts (sockets) on the battery module, i.e. that the red plug goes to the red socket. The plugs must audibly click into place. Incorrect wiring will lead to a short-circuit, and it will be necessary to exchange the battery modules. 9 ATTENTION! Noiseless battery operation cannot be guaranteed if the BAT COM communication cable is improperly connected. Ensure that connection is carried out properly in accordance with the diagram of connections from chapter 7.5. Lay the communication cable for the BAT COM using the included patch cable. Start by running the cable from the HV APU [BAT COM] to the BAT COM IN of the module installed below the HV APU. From there, run the cable from the BAT COM OUT to the BAT COM IN of the next module. The BAT COM OUT of the last battery module remains open. Attention! Ensure correct cabling from the left to the right cabinet. >> 15/33

Step 10 11 View Designation ATTENTION! Improper connection of the rack balancing cables damages the Active Battery Optimizer, which must then be replaced. Ensure that connection is carried out properly in accordance with the diagram of connections from chapter 7.5. Plug in the rack balancing plugs. Start with the battery module underneath the HV APU, where the plug with a bridge from 1 to 4 is fitted into IN, and OUT is connected to the IN of the subsequent battery module. The last battery module in the string must have the plug with a bridge from 1 to 4 fitted into its OUT terminal. Attention! Ensure correct cabling from the left to the right battery cabinet. Connect the DC cable from the STPS 60 to the HV APU (charger). The red plug for connection to the positive terminal and the black plug for connection to the negative terminal are already equipped with touch-proof plugs. Begin by connecting to the SMA STPS 60, before the plugs are connected to the HV APU. To fix the DC cables to the SMA STPS 60 and provide strain relief, fasten the clamps to the C-profile rail above the HV APU. 1 Connect the HV APU s LAN connection to the switch provided by TESVOLT. On this switch, the SMA STPS 60 is also connected to the terminal on the Ethernet interface in position G, as seen in chapter 8. Installation completed! 16/33

7.6 E-stop contact The TS HV 70 has an e-stop (emergency stop) function. An externally accessible two-pin plug (type 734-16 manufactured by WAGO) is provided on the device for this purpose. This electrical connection can be connected to an external control system via the corresponding WAGO 734-10 socket. The external control system can switch the unit off independently of the communication. There are states: 1. If contacts 1 and of the WAGO plug are connected,. If contacts 1 and of the WAGO plug are open, e.g. after e.g. via an external relay, the e-stop is inactive activating the emergency off switch, then the e-stop is and the HV APU is thus switched on. active and will be shown as active on the HV APU s display. Requirement for the external control system As there is a voltage of 4 VDC across the e-stop and these devices are used internally, an external relay is required to enable correct functioning. This relay can be adapted to the requirements of the external control system used. CAUTION! There is a voltage of 4 VDC across the e-stop based on the potential of the housing. This voltage is generated from the battery voltage, across the power supply unit integrated into the HV APU. Circuit diagram E-Stop Delivery status with E-Stop BRIDGE Single-pole relay 17/33

TESVOLT Battery Monitoring (BatMon) menu structure Battery Cells Events Parameter System Output Battery voltage Charging/discharging current Battery temperature Balancing mode Charging cycle (kwh) SoC (state of charge) SoH (state of health) Warning time Cell voltage Cell temperature SoC (cell) SoH (cell) Event logbook Battery parameters Current errors Firmware update Serial port The battery parameters are password protected. As these parameters directly affect the battery, only certified specialists may configure them. You can request the password directly from TESVOLT GmbH. SoC State of Charge This value indicates the percentage to which the battery has been charged. 100% means that the battery is fully charged. The HV APU can use parameters to determine the state of charge of a cell or battery module and stop the charging process if necessary. This prevents overcharging. The software uses the same function to monitor the discharging process, in order to avoid placing any unnecessary loads on the cells. A minimum state of charge of the battery is defined and the system stops the discharging process when this value is reached. SoH State of Health This value indicates how healthy the cell is. Precise monitoring allows the system to detect differences in performance between individual cells and thus identify damaged or faulty cells. If necessary, the system will shut down and notify the SMA STPS 60 of this. 30/33
