Danger - Electric voltage!
Electric voltage! Risk of death and fire due to electric voltage of 100 … 240 V.
Dangerous currents flow through the body when coming into direct or indirect
contact with live components. This can result in electric shock, burns or even
death.
■
Work on the 100 … 240 V supply system may only be performed by
authorised and qualified electricians.
■
Disconnect the mains power supply before installation / disassembly.
■
Never use the device with damaged connecting cables.

Do not open covers firmly bolted to the housing of the device.
■
Use the device only in a technically faultless state.
■
Do not make changes to or perform repairs on the device, on its components
or its accessories.
■
Keep the device away from water and wet surroundings.
Danger - Electric voltage!
Install the device only if you have the necessary electrical engineering
knowledge and experience.
■
Incorrect installation endangers your life and that of the user of the electrical
system.
■
Incorrect installation can cause serious damage to property, e.g. due to fire.
The minimum necessary expert knowledge and requirements for the installation

3. Ensure there is no voltage
4. Connect to earth and short-circuit
5. Cover or barricade adjacent live parts.
■
Use suitable personal protective clothing.
■
Use only suitable tools and measuring devices.
■
Check the type of supply network (TN system, IT system, TT system) to
secure the following power supply conditions (classic connection to ground,
protective earthing, necessary additional measures, etc.).
Caution - Glass breakage!
The breakage of a glass plate could lead to the risk of injury.
Thr glass plate consists of high-quality safety glass. Yet breakage cannot be
