Electrical Safety - GYS NEOCUT 105 Handbuch

FIRE AND EXPLOSION RISKS
Protect the entire working area and ensure that flammable items are stored at a distance of at least 11 meters.
Fire extinguishing equipment must be kept in close proximity when cutting materials.
Be careful of weld spatter and sparks, even through cracks. If not careful then this could potentially lead to a fire or an explosion.
Keep people, flammable materials/objects and containers that are under pressure at a safe distance.
Cutting in containers or pipes should be avoided and, if they are open, then flammable or explosive materials must be removed (oil, fuel, gas...).
Grinding operations should not be carried out close to the power supply or flammable materials.

ELECTRICAL SAFETY

The electrical mains used must have an earth terminal. Use the recommended fuse size.
An electric shock could cause serious injuries or potentially even deadly accidents.
Do not touch any live part of the machine (inside or outside) when it is plugged in (Torches, cables, clamps) because they are connected to the cutting
circuit.
Before opening the device, it is imperative to disconnect it from the mains and wait 2 minutes, so that all the capacitors are discharged.
Damaged cables and torches must be changed by a qualified technician. Make sure that the cable cross section is adequate with the usage (extensions
and welding cables). Always wear clothing that is dry and in good condition in order to shield yourself from the cutting circuit. Wear insulating shoes,
regardless of the workplace/environment in which you work in.
EMC MATERIAL CLASSIFICATION
This Class A machine is not intended to be used on a residential site where the electric current is supplied by the domestic
low-voltage power grid. There may be potential difficulties in ensuring electromagnetic compatibility at these sites, due to
conducted interferences as well as radiation.
This equipment complies with the IEC 61000-3-11 standard.
This equipment does not comply with IEC 61000-3-12 and is intended to be connected to private low-voltage systems interfacing
with the public power grid only at the medium- or high-voltage level. If connected to a public low-voltage power grid, the
installer or user of the machine has to ensure, by checking with the network operator, that the device can be connected.
ELECTROMAGNETIC INTERFERENCES
The electric current flowing through any conductor causes electrical and magnetic fields (EMF). The cutting current generates
an EMF around the cutting circuit and the cutting equipment.
The EMF electromagnetic fields can interfere with certain medical implants, such as pacemakers. Protective measures must be taken for people having
medical implants. For example, by restricting access to passers-by or conducting an individual risk evaluation for the users.
All users should take the following precautions in order to minimise exposure to the electromagnetic fields (EMF) generated by the cutting circuit:
• position the cutting cables together - if possible, attach them;
• keep your head and upper body as far as possible from the cutting circuit;
• never wrap the cable around your body;
• Never position your body between the cables. Hold both cutting cables on the same side of your body;
• Connect the earth clamp as close as possible to the area being cut;
• do not work too close to, do not lean and do not sit on the cutting machine ;
• do not cut when you're carrying the machine.
People wearing pacemakers are advised to consult their doctor before using this device.
Exposure to electromagnetic fields while welding may have other health effects which are not yet identified.
RECOMMENDATIONS FOR WELDING AREA ASSESSMENT AND CUTTING
General points
The user is responsible for the installation and use of the arc cutting equipment according to the manufacturer's instructions. If electromagnetic
disturbances are detected, the user is responsible for resolving the situation with the manufacturer's technical support. In certain cases, this corrective
action may be as simple as earthing the cutting circuit. In other cases, it may be necessary to construct an electromagnetic shield around the cutting
power source and around the entire piece by fitting input filters. In all cases, electromagnetic interferences must be reduced until they are no longer
an issue.
