10
An electric shock is life-threatening and may be deadly.
Do not touch voltage-carrying parts inside or outside of the device.
All cables and leads must be secured, undamaged, insulated, and adequately
dimensioned. Replace loose connections and scorched, damaged, or inade-
quately 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 result-
ing from improper use.
Have the grid and device supply lead regularly inspected by an electrician to
ensure 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 de-
vice switched on again by affixing a clearly legible and understandable warn-
ing sign.
After opening the device:
- Discharge all electrically charged components
- Ensure that all components are disconnected from the power supply
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.
Devices in emission class A:
- Are only designed for use in industrial settings
- Can cause line-bound and radiated interference in other areas
Devices in emission class B:
- Satisfy the emissions criteria for residential and industrial areas.
This is also true for residential areas in which the energy is sup-
plied from the public low-voltage grid.
