Where necessary, the connection of the workpiece to earth should be made by a direct connection to the workpiece, but in some countries where direct connection is not permitted, the bonding should be achieved by suitable capacitances selected according to national regulations. Care should be taken to prevent the earthing of the workpiece increasing the risk of injury to users, or damage to other electrical equipment. Where the workpiece is not bonded to earth for electrical safety, nor connected to earth because of its size and position, for example, ship’s hull or building steelwork, a connection bonding the workpiece to earth may reduce emissions in some, but not all instances. The operator should be insulated from all such bonded metallic components. However, metallic components bonded to the workpiece will increase the risk that the operator could receive a shock by touching these metallic components and the electrode (nozzle for laser heads) at the same time. The cutting cables should be kept as short as possible and should be positioned close together, running at or close to the floor level.īonding of all metallic components in the cutting installation and adjacent to it should be considered. In particular, the spark gaps of arc striking and stabilizing devices should be adjusted and maintained according to the manufacturer’s recommendations. The cutting equipment should not be modified in any way except for those changes and adjustments covered in the manufacturer’s instructions. All access and service doors and covers should be closed and properly fastened when the cutting equipment is in operation. The cutting equipment must be routinely maintained according to the manufacturer’s recommendations. The shielding should be connected to the cutting mains supply so that good electrical contact is maintained between the conduit and the cutting power source enclosure. Shielding should be electrically continuous throughout its length. Consideration should be given to shielding the supply cable of permanently installed cutting equipment, in metallic conduit or equivalent. If interference occurs, it may be necessary to take additional precautions such as filtering of the mains supply. The surrounding area may extend beyond the boundaries of the premises.Ĭutting equipment must be connected to the mains supply according to the manufacturer’s recommendations. The size of the surrounding area to be considered will depend on the structure of the building and other activities that are taking place. Time of day that cutting or other activities are to be carried out. This may require additional protection measures. User shall ensure that other equipment being used in the environment is compatible. Immunity of other equipment in the environment. Equipment used for calibration or measurement. Health of the people around, for example the use of pacemakers and hearing aids.į. Safety critical equipment, for example guarding of industrial equipment.Į. Radio and television transmitters and receivers.ĭ. Other supply cables, control cables, signalling and telephone cables above, below and adjacent to the cutting equipment.ī. The following shall be taken into account:Ī. In all cases electromagnetic disturbances must be reduced to the point where they are no longer troublesome.īefore installing the equipment the user shall make an assessment of potential electromagnetic problems in the surrounding area. ![]() ![]() In other cases it could involve constructing an electromagnetic screen enclosing the power source and the work complete with associated input filters. In some cases this remedial action may be as simple as earthing the cutting circuit, see Earthing of Workpiece. If electromagnetic disturbances are detected then it shall be the responsibility of the user to resolve the situation with the technical assistance of the manufacturer. The user is responsible for installing and using the plasma equipment according to the manufacturer’s instructions. This cutting equipment is designed for use only in an industrial environment. In such cases it may be necessary to use other measures to further reduce interference. The limits required by EN60974-10 may not be adequate to completely eliminate interference when the affected equipment is in close proximity or has a high degree of sensitivity. The equipment should be installed and used in accordance with the information below to achieve electromagnetic compatibility. Hypertherm’s CE-marked equipment is built in compliance with standard EN60974-10.
