Safety Instructions

All products are intended as an utility device for development under laboratory conditions. For use or operation specialist knowledge is required.

Electrical Circuits

  • The usual precautionary measures when handling electrical voltages have to be observed. Work on the mains voltage or above the safety extra-low voltage may only be done by qualified electricians.
  • Electrostatic discharge (ESD) can instantly destroy electronics if you do not take appropriate precautions.
  • Inductive and capacitive voltage spikes can instantly and unexpectedly destroy electronics when you apply power, even if you are careful about electrostatic discharge (ESD).
  • Fully charged batteries can have a significantly higher voltage than their nominal voltage value.
  • Wall wart power adapters are often unregulated, so that a 9V adapter might initially output 12V and with the voltage dropping as the load increases.
  • Breadboards and jumper wires are not appropriate for carrying high currents.
  • Connectors (pin headers) only have a contact when they are soldered to the PCB.


  • Mechanical damage or strong thermal stress can cause internal short circuits, which can lead to high currents and thus to high heating.
  • Lithium is a highly reactive metal. Burning batteries with lithium are not allowed to extinguished with water, please use for example sand.
  • Damaged batteries have to be disposed of in appropriate safety containers immediately.
  • Do not leave rechargeable batteries unattended while charging and pay attention the respective charging voltage and current.


  • The usual protection and precautionary measures when handling laser radiation and high power light sources have to be observed.
  • We strongly recommend wearing appropriate safety glasses when working with laser or high power light sources.


  • Be careful when handling strong magnets (e.g. made of neodymium) to prevent pinching and splintering due to their brittleness.
  • Magnets create a far-reaching and strong magnetic field. Among other things, they can damage or harm computers, memory disks, credit cards or pacemakers.


  • The usual protection and precautionary measures when handling chemicals have to be observed.
  • Further necessary preventatives can be taken from the product label and packaging and the safety data sheet.


Manuals, instructions and datasheets can be found online on the respective manufacturer websites due to their large scope and actuality, if they are not shipped with the product. For use and operation of the products an Internet-enabled computer is required to retrieve information and to install appropriate configuration software. If you have further questions, please contact us by mail.

Waste Disposal

Electrical Appliances

Electrical and electronic appliances that have become waste are referred to as old or waste appliances and old appliances may not be disposed of as general household waste.

The symbol of a crossed waste bin regularly shown on electrical and electronic equipment indicates that at the end of its service life the respective appliance has to be kept separate from unsorted general municipal waste.

If the old appliance has a removable battery (or accumulator), then please remove it and dispose of it separately if defective.

Information and telecommunications equipment often contains sensitive personal information. The end user is responsible for the respective deletion of the data on old appliance.

The return/disposal of old appliances from private households can take place at municipal waste collection points / recycling centers or at the collection points set up by manufacturers/resellers within the meaning of the ElektroG (Electrical and Electronic Equipment Act). Small electric appliance can be sent sufficiently stamped to us for proper disposal or handed over on site free of charge.


Batteries may not disposed of with general household waste and end users are legally obliged to return used batteries.

The waste bin symbol indicates pollutant-containing batteries as well as the fact that batteries disposed of properly. Near the waste bin symbol is the chemical name of the metals contained in the battery. “Cd” stands for cadmium, “Pb” for lead and “Hg” for mercury.

You can hand over waste batteries at a municipal waste collection point / recycling center or send them sufficiently stamped to us for proper disposal or deliver them on site free of charge.
