Dangers due to An electric shock is life-threatening and may be deadly.
Mains Current
Do not touch voltage-carrying parts inside or outside of the device.
and Operating
Current
All cables and leads must be secured, undamaged, insulated, and adequately di-
mensioned. Replace loose connections and scorched, damaged, or inadequately
dimensioned cables and leads immediately.
Do not wrap cables or leads around your body or parts of the body.
Only put the device into operation if it is correctly connected on the output side.
Operate the device only on a grid with a ground conductor and a socket with a
ground conductor contact.
Operating the device on a grid without a ground conductor is considered to be
grossly negligent. The manufacturer is not responsible for any damage resulting
from improper use.
Have the grid and device supply lead regularly inspected by an electrician to en-
sure that the ground conductor is functioning properly.
Switch off unused devices.
Before working on the device, disconnect the mains plug.
Secure the device to prevent the mains plug from being connected and the
device switched on again by affixing a clearly legible and understandable warning
sign.
After opening the device:

If work is needed on voltage-carrying parts, bring in a second person who will
switch off the main switch at the correct time.
The housing screws act as a ground conductor connection for grounding the
housing. The screws must not under any circumstances be replaced by other
screws without a reliable ground conductor connection.

instruct them about all dangers (blinding hazard due to arcs, injury hazard
due to flying sparks, welding fume hazardous to health, noise exposure, pos-
sible hazard due to mains current or welding current, possible hazard due to
electromagnetic fields, possible hazard due to the magnetic field of the
cleaning aperture, moving mechanical parts, compressed air/parting agent
mixture discharged from the cleaning aperture, flying chips or similar, etc.),
provide suitable protective equipment, or
construct suitable protective walls and curtains.
Discharge all electrically charged components
Ensure that all components are disconnected from the power supply
Are only designed for use in industrial settings
Can cause line-bound and radiated interference in other areas
Satisfy the emissions criteria for residential and industrial areas. This is also
true for residential areas in which the energy is supplied from the public low-
voltage grid.
