Before opening a device, always unplug the power plug or make sure that the device is de-energized. Components, assemblies or devices may only be put into operation if they have been installed in a housing in a touch-proof manner beforehand. During installation, they must be de-energized.

Tools may only be used on devices, components or assemblies if it is ensured that the devices are disconnected from the supply voltage and electrical charges stored in the components located in the device have been discharged beforehand.

Live cables or lines to which the device, component or assembly is connected must always be checked for insulation defects or breakages. If a fault is detected in the supply line, the device must be taken out of operation immediately, until the defective line has been replaced. When using components or assemblies, it must always be ensured that the characteristic data for electrical quantities specified in the corresponding description are strictly adhered to be pointed out. If it is not clear from a present description for the non-commercial end user which electrical characteristic values apply to a component or an assembly, how an 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, then a specialist must always be requested for information.
