Installation
Please read and understand our general information before starting the installation.
Structure
Housing
The Hub S is housed in a module rack that has been specifically designed for this application. The rack provides a stable and protected environment for all the components.
Batterie mounting
The Frame S is installed in the rack, accommodating up to four Battery S units with a precise fit and mechanically securing them — also suitable for transport.
Charging electronics
The charging electronics are mounted on a separate mounting plate in the rear section of the Hub S. They control the charging process of all installed Battery S units.
Mains connection
On the rear side of the housing, there is an IEC 60320 C14 inlet with an integrated main switch and fuse. Power is supplied via a 230 V AC source.
Installation Guidelines
- Install the Hub S as a freestanding unit on a level, stable surface (table or floor) — no wall or floor mounting required.
- Maintain a minimum clearance of 100 mm on all sides from walls, furniture, and flammable materials.
- Do not cover ventilation openings.
- Do not expose the device to direct sunlight and do not install it near heat sources.
- Stack a maximum of 2 Hub S units on top of each other (observe stability, ventilation, and maximum total weight).
Electrical Installation & Grounding
- Visually inspect the power cable, socket, fuse, and main switch for damage.
- Set the main switch on the Hub S to 0. Fully insert the device-side connector of the power cable.
- Connect the mains plug to a properly protected 230 V socket.
- Continuity test between PE connection and housing: resistance < 0.3 Ω (low-resistance measurement according to DIN VDE 0100-600).
- Insulation test between phase conductor and PE: > 1 MΩ at 500 V DC.
- Perform an RCD test on the supplying circuit.
Commissioning
- Check correct installation and ventilation clearances (see section Installation).
- Protective earth (PE) test successfully completed (see section Electrical Installation).
- Set the main switch on the Hub S to 0. Connect the power cable between the Hub S and a 230 V socket. Then switch the main switch to I.
- Insert up to four Battery S modules (see section Inserting Battery S) and check the status LEDs on each module.
- If commissioning is successful, the LEDs on the Battery S will light up — the charging process starts automatically.
- Perform a functional test by checking the status/LED indicators on the Hub S.
- Complete the commissioning report (see section Commissioning Checklist) and have it signed by the operator.

Operation
Inserting the Battery S
- Insert the Battery S into the guide rail as shown in the illustration. The locking lever must be foldable to the left.
- Make sure the battery is positioned correctly (handle must be able to fold out from right to left).
- Use the handle to slide the battery into the holder until it reaches the stop. Secure it by tilting the handle to the right and locking it into place.
- When the Battery S is correctly inserted, the Battery S LEDs will illuminate.
Removing the Battery S
- Ensure that the charging process is complete (check LED status).
- Move the lever on the Battery S to the left to unlock it.
- Remove the Battery S from the Frame S using the lever.
Charging Process
- Up to four Battery S modules can be charged simultaneously.
- The Hub S automatically distributes the total charging current of 60 A among the inserted modules.
- Typical charging time: 5–6 hours for four fully discharged Battery S modules.
- Do not cover the Hub S during the charging process.
Status Indicators
The Battery Hub S itself has no dedicated status LEDs. The operating status is indicated exclusively by the LEDs of the inserted Battery S modules:
| Battery S LED indication | Meaning |
|---|---|
| LED solid green | Module correctly inserted, charging process active |
| LED flashing | Charging level reached or fault — see Battery S manual |
| LED off | Module not inserted, OFF mode, or Hub S not powered |
For detailed Battery S error codes, refer to the Battery S user manual, section “Troubleshooting”.
Maintenance
Cleaning and care
- Clean the exterior with a damp cloth. Do not use aggressive chemicals or high-pressure cleaners.
- Clean the interior (Frame S, ventilation openings) using only dry compressed air or a soft brush.
- Regularly check ventilation grilles for dust and contamination.
NOTE:
After each maintenance, a comprehensive functional test must be carried out and documented in writing. When replacing components, only original spare parts may be used. Maintenance must only be performed by authorized and trained personnel.
Visual inspection:
- Check the housing for damage
- Clean the device if contaminated
- Check Frame S for damage / wear
- Check the power inlet, cable, main switch, and fuse holder for damage; verify the fuse rating
Electrical inspection:
- Perform inspection in accordance with DGUV V3 (DIN VDE 0701/0702)
- Protective conductor resistance < 0.3 Ω
- Insulation resistance > 1 MΩ
- Functional test of the charging process with a reference Battery S

Why is there no voltage at the battery’s power output?
Make sure the battery is not in OFF mode and that no error message appears when pressing a button. Error codes for the Battery S can be found in the corresponding operating manual.
Behavior in Case of Fire and Emergency
Behavior in case of odor, smoke, or unusual heating:
- Immediately maintain a safety distance of at least 10 m.
- Evacuate and secure the area.
- If it can be done safely: set the main switch to 0 and disconnect the power cable — alternatively, disconnect the mains supply at an external isolation point.
- Do not attempt to remove individual Battery S modules from a smoking Hub S.
- Alert the fire brigade, keyword: “Lithium battery fire, incident location …”.
- Inform BOS Service: +49 (0) 731 7254 4107.
- Hazard classification of the Battery S: UN 3480, Class 9 (lithium-ion batteries)
- Recommended extinguishing agents: large quantities of water for cooling the modules; alternatively sand for covering
- Do not use CO₂ or dry powder extinguishers as primary extinguishing agents — they do not provide sufficient cooling
- Wear personal protective equipment with self-contained breathing apparatus
- Fire gases may contain hydrofluoric acid (HF), carbon monoxide (CO), and carbon dioxide (CO₂)
- Monitor the fire site for at least 72 hours after extinguishing (risk of re-ignition)
- Safety data sheet: available at
Damaged battery S modules
- Do not continue operating modules with visible damage, deformation, odor emission, or heat development in the Hub S
- Remove the module from the Frame S using insulated tools and store it outdoors in a non-combustible container (e.g. steel box with sand)
- Consult BOS Service before taking any further action
Storage & Decommissioning
- Remove all Battery S modules from the Hub S and store them in accordance with the Battery S manual (typically 80–90% SoC, in a cool and dry place).
- Set the main switch to 0 and disconnect the power cable.
- Store the Hub S in a dry, low-dust environment.
- Temperature: +10 °C to +25 °C (recommended; permissible range −20 °C to +50 °C)
- Relative humidity: max. 50% non-condensing (optimal 30–45%)
- Climate-controlled indoor areas, dry, dust-free, well-ventilated
- Protect from moisture, water, salt spray, and corrosive vapors
- Avoid direct sunlight and temperature fluctuations leading to condensation
Transportation
The Hub S itself does not contain any batteries and is therefore not subject to hazardous goods regulations. Please observe the following points during transport:
- Remove all Battery S modules prior to transport
- Pack the power cable separately
- Use the original packaging if available; otherwise, secure the device against impacts
- Observe the weight of 21 kg — use a two-person lift or suitable lifting equipment
Classification UN 3480, Class 9. Please refer to the Battery S operating instructions as well as the ADR regulations (road transport) and IATA-DGR (air transport).
