Important Information and Disclaimer
Please read the instructions of usage before setting up or operating our products.
Our products are designed for development, research and teaching purposes only! You are responsible for compliance with the technical regulations.
When handling products that come into contact with electrical voltage, the applicable VDE regulations must be observed, in particular VDE 0100, VDE 0550/0551, VDE 0700, VDE 0711 and VDE 0860. Before opening a unit, always disconnect the mains plug or ensure that the unit is current-free. Components, assemblies or devices may only be put into operation if they have been previously installed in an enclosure so that they are safe from accidental contact. They must be current-free during installation.
Tools may only be used on devices, components or assemblies if it has been ensured that the devices are disconnected from the supply voltage and that electrical charges stored in the components located in the device have been discharged beforehand.
Live cables or lines to which the unit, component or assembly is connected must always be inspected for insulation faults or breaks. If a fault is detected in the supply line, the unit must be taken out of operation immediately until the defective line has been replaced. When using components or assemblies, it must always be pointed out that the characteristic data for electrical variables specified in the associated description must be strictly adhered to. If it is not clear for the non-professional end user from an existing description which electrical characteristic values apply to a component or assembly, how external wiring is to be carried out or which external components or additional devices may be connected and which connection values these external components may have, an expert must always be consulted for information. Before putting a unit into operation, it must generally be checked whether this unit or assembly is fundamentally suitable for the application for which it is to be used!
In case of doubt, it is absolutely necessary to consult specialists, experts or the manufacturers of the assemblies used!
Please note that operating and connection errors are beyond our control. Understandably, we cannot accept any liability for damage resulting from them. In the event of malfunction, kits should be returned with an exact description of the fault (stating what is not working, as only an exact description of the fault will enable a faultless but chargeable repair!) and the associated assembly instructions, as well as without the housing. For understandable reasons, we have to charge extra for time-consuming assembly or disassembly of housings. Kits that have already been assembled are excluded from exchange. It is essential to observe the VDE regulations when installing and handling mains voltage. Devices that are operated at a voltage above 35 V may only be connected by a specialist. In any case, it must be checked whether the kit or the circuit board is suitable or can be used for the respective application and place of use.
According to DIN VDE 0869, the person who completes a kit or makes an assembly ready for operation by extending it or installing it in a housing is considered to be the manufacturer and is obliged to supply all accompanying documents and also to state his name and address when passing on the device. Devices that are assembled from kits are to be regarded as an industrial product in terms of safety.
Intended Usage (operating conditions)
Our modules have been developed as experimentation and learning boards. They are not suitable for taking over tasks in productive operation. The modules are intended for use in dry and clean rooms. Any other use is not permitted.
The non-intended use of our products can damage or destroy them, which is associated with hazards such as short-circuit; fire, electric shock, radio interference, etc. The products must not be modified or converted. Under no circumstances may 230V network voltage be connected - there is a danger to life. The modules may only be operated at the voltage specified for them. In the case of units with an operating voltage of 35 volts or more, final assembly may only be carried out by a specialist in compliance with the VDE regulations. The operating position of the unit is arbitrary.
When installing the units, ensure that the cable cross-section of the connection lines is sufficient! The connected loads must be connected in accordance with the VDE regulations. The permissible ambient temperature (room temperature) must not exceed or fall below 0°C and 40°C during operation.
If condensation forms, wait for an adaptation period of up to 2 hours. In commercial facilities, the accident prevention regulations of the German Federation of Institutions for Statutory Accident Insurance and Prevention (Verband der gewerblichen Berufsgenossenschaften) for electrical systems and equipment must be observed.
In schools, training facilities, hobby and self-help workshops, the operation of assemblies must be supervised responsibly by trained personnel.
Do not operate the modules in an environment in which flammable gases, vapours or dusts are or may be present.
If the unit ever needs to be repaired, only original spare parts may be used! The use of other spare parts can lead to serious damage to property and personal injury!
If any liquid enters the unit, it could be damaged.
Please note that the legal regulations must be observed when operating a radio module. These regulations govern channel use, transmission power, etc.! Operation may only take place in approved frequency ranges with the maximum permitted transmission power and transmission duration. Please obtain this information from the respective competent authority. For Germany, you can find this information under www.bundesnetzagentur.de . Please also refer to the data sheet of the radio module manufacturer.
Liability, EMC conformity
All parts of the circuit have been carefully checked and tested. Nevertheless, we can of course not guarantee that everything will work perfectly. In particular, we accept no liability for damage caused by rebuilding, commissioning etc. of the circuits presented on our website or in our documentation. The person assembling the kit or project is considered the manufacturer and is therefore responsible for compliance with the applicable safety and EMC directives and regulations.
Unless otherwise stated, all PCBs, kits, modules and boards are generally "non-CE approved" components and are designed for installation in equipment or enclosures. CE standards must be observed during use. The purchaser is responsible for this.
Liability is generally excluded for damage caused by faulty assembly, directly or indirectly. Claims for damages which do not concern injury to life, body or health are excluded if they are not based on a deliberate or grossly negligent breach of obligation. Insofar as we are liable, our liability does not include such damages that could not typically be expected. Liability and claims for damages are limited to the order value / component value. In the case of the delivery of third-party products as well as software, the special licensing or other conditions of the manufacturer shall apply in addition to these conditions.
