Compliance Information EMC-1

Introduction

Hypertherm’s CE-marked equipment is built in compliance with standard EN60974-10. The equipment should be in stalled and used in accordance with the information be low to achieve elec tro mag net ic com pat i bil i ty.

The limits required by EN60974-10 may not beadequate to com plete ly eliminate interference whenthe affected equip ment is in close proximity orhas a high degree of sen sitivity. Insuch cases itmay be nec essary to use other mea sures to furtherre duce interference.

This cutting equipment is designed for use onlyin an in dus tri al environment.

Installation and use

The user is responsible for installing and usingtheplasma equipment according to the manufacturer’s instructions. If elec tromagnet ic disturbances are de tect ed then it shall be the respon si bil i ty of the user to re solve the situation withthe technical as sis tance of the man u fac tur er. Insome cases this remedial action may be as sim ple as earthing the cuttingcircuit, see Earthingof Workpiece. Inother cas es it could involve constructing an electromag net ic screen enclosing the pow er source and the work complete with associated input filters. In all cases elec tro mag net ic disturbanc es must be reduced to the point where they are no longer trou ble some.

Assessment of area

Before installing the equipment the user shall make an assessment of po ten tial

electromagnet ic problems in the sur round ing area. The following shall be taken into account:

a. Other supply cables, control cables,

signalling and telephone ca bles; above, below and adjacent to the cutting equipment.

b. Radio and television transmitters and

receivers.

c. Computer and other control equip ment.

d. Safety critical equipment, for example

guarding of industrial equipment.

e. Health of the people around, for example the

use of pacemakers and hear ing aids.

f. Equipment used for calibration or

measurement.

g. Immunity of other equipment in the

environment. User shall ensure that other equipment being used in the environment is com pat i ble. This may require ad di tion al protection measures.

h. Time of day that cutting or other ac tiv i ties

are to be carried out.

The size of the sur round ing area to be considered will depend on the structure of the building and other activities that are taking place. The surrounding area may ex tend beyond the bound aries of the pre mises.

Methods of reducing emissions

Mains supply

Cutting equipment must be con nect ed to the mains supply according to the man u fac tur er’s

recom men da tions. If in ter fer ence occurs, it may

ELECTROMAGNETIC COMPATIBILITY EMC

9/10

EMC-2 Compliance Information

be necessary to take addi tional precautions such as fil ter ing of the mains supply. Consideration should be given to shield ing the supply cable of per ma nent ly installed cutting equip ment, in metallic conduit or equiv a lent. Shielding should beelec tri cal ly continuous through out its length. The shielding should becon nect ed to the cutting mains supply so that good electrical contact is maintained between the conduit and the cutting pow er source enclosure.

Maintenance of cutting equipment

The cutting equipment must be rou tine ly maintained according to the man u fac tur er’s recom men da tions. All ac cess and service doors and covers should be closed and properly fastened when the cutting equip ment is in operation. The cutting equipment should not be modified in any way except as set forth in and in accordance with the manufacturer’s written instructions. For example, the spark gaps of arc striking and sta bi liz ing devices should be adjusted and maintained according to the manu fac tur er’s recommendations.

Cutting cables

The cutting cables should be kept as short aspossible and should be po si tioned close together, running at or close to the floor level.

Equipotential bonding

Bonding of all metallic components in the cutting installation and adjacent to it should be considered. However, metallic com po nents bonded to the workpiece will increase the risk that the op er a tor could receive a shock by touch ing these metallic compo nents and the electrode (nozzle for laser heads) at the same time. The op er a tor should be in su lat ed from all such bonded metallic components.

Earthing of workpiece

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 steel work, a con nec tion bonding the work piece to earth may reduce emis sions in some, but not all instances. Careshould be takento prevent the earthing ofthe work piece increasing the risk of injury to users, or damage to other elec tri cal equipment. Where necessary, the con nec tion of the workpiece to earth should be made by a direct connection to the work piece, but in some countries where direct connection is not permitted, the bonding should be achieved by suit able capacitances se lect ed according to national regulations.

Note: the cutting circuit may or may not be earthed for safety reasons. Changing the earthing arrangements should only be authorized by a person who is com pe tent to assess whether the chang es will in crease the risk of injury, for example, by al low ing parallel cutting cur rent return paths which may damage the earth cir cuits of other equipment. Further guid ance is provided in IEC 60974-9, Arc Welding Equip ment, Part 9: Installation and Use.

Screening and shielding

Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems of in ter ference. Screening of the entire plas ma cutting installation may be con sid ered for special applications.
