1.4 Classification of the arnings
The warnings are divided into four different categories and are indicated
prior to potentially dangerous work steps. The following signal words are
used depending on the type of hazard:
2 Safety
This chapter warns of residual hazards that should be kept in mind to
operate the product safely. Non-observance of the safety instructions may
result in risks to the life and health of personnel, and environmental
damage or material damage.
• Observe the document entitled “Safety Instructions”.
2.1 Designated use
The device described in this documentation may be used only for the
purpose and in the manner described. The device is used only for the
generation and control of the output current required for plasma cutting
and gouging. Any other use is considered improper. Unauthorized
modifications or changes to enhance the performance are not permitted.
• Do not exceed the maximum load data as defined by the
documentation supplied. Overloads lead to destruction.
• Do not make any constructive changes to this product.
• Do not use the device to thaw pipes.
• Do not use or store the device outdoors where it is wet.
DANGER
Describes an imminent threatening danger. If not avoided, it may cause
severe injuries or death.
WARNING
Describes a potentially dangerous situation. If not avoided, this may
result in death or serious injuries.
CAUTION
Describes a potentially harmful situation. If not avoided, this may result in
slight or minor injuries.
NOTICE
Describes the risk of impairing work results or material damage and
indicates irreparable damage to the device or equipment.

EX-TRAFIRE®05HD 2 Safety

2.2 Obligations of the operator
• Ensure that only qualified personnel are permitted to perform work on
the device or system.
Authorized personnel are:
— those who are familiar with the basic regulations on occupational
safety and accident prevention;
— those who have been instructed on how to handle the device;
— those who have read and understood these operating instructions;
— those who have been trained accordingly;
— those who are able to recognize possible risks because of their
special training, knowledge, and experience.
• Keep untrained persons out of the work area.
• Each time the devicor another authorized specialist perform a safety
inspection in accordance with DIN IEC 6097 Part : “Periodic
inspection and testing”.
The device can produce electromagnetic fields that could impact the
proper function of cardiac pacemakers and implanted defibrillators.
• Do not use the device if you have a pacemaker or an implanted
defibrillator.
This Class A cutting device is not intended for use in residential areas with
a public low-voltage power supply system. It can potentially be difficult to
guarantee electromagnetic compatibility in these areas due to both
conducted and emitted interference.
• The device may be used only in industrial zones according to
DIN EN 61000-6-3.
2.3 Warning and notice signs
The following warning, notice and mandatory signs can be found on the
product:
These markings must always be legible. They may not be covered,
obscured, painted over, or removed.
2.4 Product-specific safety instructions
• Do not use or store the device outdoors where it is wet.
• Do not operate the device if the housing is open.
• Read and observe the operating instructions.

2.5 Safety instructions for the electrical po er supply
• Ensure that the input power cable is not damaged, for example, by
being driven over, crushed or torn.
• Check the input power cable for damage and wear at regular intervals.
• If it is necessary to replace the input power cable, only models indicated
by the manufacturer may be used.
• Only a qualified electrician should carry out work on the input power
cable and the mains plug.
• Splash-water protection and mechanical stability must be ensured when
replacing the mains plug of the input power cable.
2.6 Safety instructions for plasma cutting
• Plasma cutting may cause damage to the eyes, skin, and hearing. Note
that other hazards may arise when the device is used with other cutting
components. Therefore, always wear the prescribed personal protective
equipment as defined by local regulations.
• All metal vapors, especially lead, cadmium, copper, and beryllium, are
harmful. Ensure sufficient ventilation or extraction. Do not exceed the
current occupational exposure limits (OEL).
• To prevent the formation of phosgene gas, rinse workpieces that have
been degreased with chlorinated solvents using clean water. Do not
place degreasing baths containing chlorine in the vicinity of the cutting
area.
• Adhere to the general fire protection regulations and remove
flammable materials from the vicinity of the cutting work area prior to
starting work. Provide appropriate fire extinguishing equipment in the
workplace.
2.7 Personal protective equipment
• Wear your personal protective equipment (PPE).
• Ensure that others in close proximity are also wearing personal
protective equipment.
Personal protective equipment consists of protective clothing, safety
goggles, face protection, ear protectors, protective gloves, and safety
shoes.
