Danger from
mains current
An electric shock can be fatal.
Do not touch voltage-carrying parts inside or outside the device.
All cables and leads must be secured, undamaged, insulated, and adequately dimen -
sioned. 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.
Have the mains and device supply lead regularly inspected by an electrician to ensure that
the ground conductor is functioning properly.
Only operate the device on a grid with a ground conductor and a socket with a ground con -
ductor contact.
Operating the device on a grid without a ground conductor and on a socket without a
ground conductor contact is considered gross negligence. The manufacturer accepts no
liability for any damage resulting from improper use.
Switch off unused devices.
When working at elevated heights, wear a safety harness to prevent falls.
Before working on the device, switch off the device and remove the mains plug.
Secure the device to prevent the mains plug from being connected and switched on again
by applying a clearly legible and understandable warning 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.
Repair work (e.g., opening the device) must only be carried out by qualified personnel
trained for this purpose. If a defect occurs, unplug the device immediately and have the
repair carried out by trained and qualified personnel.
- Repairs must only be carried out in a de-energized state
- Only use original spare parts
- Only unplug the device when it is switched off
EMC device clas -
sifications
The Virtual Welding system is an emission class A device
Devices in emission class A
- Are only designed for use in industrial areas
- Can cause wiring-related or radiated interference in other areas.
In certain cases, even though a device complies with the standard limit values for emis -
sions, it may affect the application area for which it was designed (e.g., when there is sen -
sitive equipment at the same location, or if the site where the device is installed is close to
either radio or television receivers).
