Particular hazard
areas
Operation or storage of the device outside the stipulated area will be deemed
as not in accordance with the intended purpose. The manufacturer is not re-
sponsible for any damage resulting from improper use.

- During operation: 0°C to + 40°C (32°F to 104°F)
- During transport and storage: -25°C to +55°C (-13°F to 131°F)
Relative humidity:
- Up to 50% at 40°C (104°F)
- Up to 90% at 20°C (68°F)
Ambient air: free of dust, acids, corrosive gases or substances, etc.
Altitude above sea level: up to 2000 m (6500 ft.)
The operating company must only allow persons to work with the device if they
- Are familiar with the basic occupational safety and accident prevention
regulations and are trained in handling the device
- Have read and understood these Operating Instructions, especially the
section "Safety Rules," and have confirmed this with their signature
- Are trained according to the requirements for the work results
The safety-conscious work of the personnel must be checked regularly.
All persons who are assigned to work with the device must do the following
before beginning the work:
- Follow the basic regulations for occupational safety and accident preven-
tion
- Read these Operating Instructions, especially the section "Safety Rules,"
and confirm that they have understood and will follow them by signing
Before leaving the workplace, ensure that no personal injury or property dam-
age can occur in one's absence.
Do not linger in the operating area of the robot.
Always integrate the device into a higher-level safety system in a secured ar-
ea.
If this area has to be accessed for preparatory or maintenance work, ensure
that
- the entire system is shut down for the duration of access to this area
- and remains shut down to prevent unintended operation, e.g., as a result
of a control error
In addition to these Operating Instructions, the safety rules of the robot man-
ufacturer must be followed.
Covers and side parts must only be opened/removed during maintenance and
repair work.
During operation:
- Ensure that all covers are closed and all side parts have been mounted
properly.
- Keep all covers and side parts closed.

Personal Protec-
tion and Protec-
tion of Others
Electromagnetic fields may cause health problems that are not yet known:
- Effects on the health of persons close by, for example those with pace-
makers, metal implants and hearing aids
- General prohibition for persons with pacemakers: Persons with pacemak-
ers must seek advice from their doctor before working with the device or
being in the immediate vicinity of the device
- General prohibition for persons with metal implants: Persons with metal
implants must seek advice from their doctor before working with the de-
vice or being in the immediate vicinity of the device
Magnetic fields generated by high amperage may eject ferromagnetic parts,
such as spatter accumulations, from the cleaning aperture. To prevent injury,
always wear protective goggles with side protection and never look into the
cleaning aperture when the device is switched on.
You are exposed to numerous hazards while handling the device, for example:
- Flying sparks and pieces of hot metal
- Arc radiation that poses a risk of injury to the eyes and skin
- Electrical risks from mains current and welding current
- Increased noise exposure
- Harmful welding fumes and gases
Wear suitable protective clothing when dealing with the device. The protective
clothing must have the following properties:
- Flame resistant
- Insulating and dry
- Covering the entire body and in good condition with no damage
- Safety helmet
- Cuffless pants
Protective clothing involves the following:
- Protecting the face and eyes from UV radiation, heat and flying sparks
with a face guard featuring a regulation-compliant filter
- Wearing regulation-compliant protective goggles with side protection be-
hind the face guard
- Wearing rigid, wet-insulating footwear
- Protecting hands with appropriate gloves (featuring electrical insulation
and thermal protection)
- Wearing ear protection to reduce noise exposure and protect against in-
jury
Keep persons, especially children, away during the operation of the devices
and during the welding process. If persons are in the vicinity, however:
- instruct them about all dangers (blinding hazard due to arcs, injury hazard
due to flying sparks, welding fume hazardous to health, noise exposure,
possible 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 sim-
ilar, etc.),
- provide suitable protective equipment, or
- construct suitable protective walls and curtains.

Dangers due to
Mains Current
and Operating
Current
EMC Device Clas-
sifications
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.
