ELECTROMAGNETIC COMPATIBILITY EMC
Introduction
Hypertherm’s CE-marked equipment is built in compliance with standard EN60974-10. The equipment should be installed and used in accordance with the information below to achieve electromagnetic compatibility.
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. In such cases it may be necessary to use other measures to further reduce interference.
This cutting equipment is designed for use only in an industrial environment.
Installation and use
The user is responsible for installing and using the plasma equipment according to the manufacturer’s instructions.
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. In some cases this remedial action may be as simple as earthing the cutting circuit, see Earthing of the workpiece. In other cases, it could involve constructing an electromagnetic screen enclosing the power source and the work complete with associated input filters. In all cases, electromagnetic disturbances must be reduced to the point where they are no longer troublesome.
Assessment of area
Before installing the equipment, the user shall make an assessment of potential electromagnetic problems in the surrounding area. The following shall be taken into account:
a. Other supply cables, control cables, signaling and
telephone cables; above, below and adjacent to the cutting equipment.
b. Radio and television transmitters and receivers.
c. Computer and other control equipment.
d. Safety critical equipment, for example guarding
ofindustrial equipment.
e. Health of the people around, for example the use
ofpacemakers and hearing 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 compatible. This may require additional protection measures.
h. Time of day that cutting or other activities are to be
carried out.
The size of the surrounding area to be considered will depend on the structure of the building and other activities that are taking place. The surrounding area may extend beyond the boundaries of the premises.
Methods of reducing emissions
Mains supply
Cutting equipment must be connected to the mains supply according to the manufacturer’s recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of the mains supply.
Compliance Information EMC-1
7/ 10
ELECTROMAGNETIC COMPATIBILITY
Consideration should be given to shielding the supply cable of permanently installed cutting equipment, in metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. 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.
Maintenance of cutting equipment
The cutting equipment must be routinely maintained according to the manufacturer’s recommendations. All access and service doors and covers should be closed and properly fastened when the cutting equipment 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 stabilizing devices should be adjusted and maintained according to the manufacturer’s recommendations.
Cutting cables
The cutting cables should be kept as short as possible and should be positioned close together, running at or close to the floor level.
Earthing of the 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 connection bonding the workpiece to earth may reduce emissions in some, but not all instances. 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 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.
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 competent to assess whether the changes will in crease the risk of injury, for example, by allowing parallel cutting current return paths which may damage the earth circuits of other equipment. Further guidance is provided in IEC60974-9, Arc Welding Equip ment, Part 9: Installation and Use.
Screening and shielding
Equipotential bonding
Bonding of all metallic components in the cutting installation and adjacent to it should be considered.
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 operator should be insulated from all such bonded metallic components.
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems of interference. Screening of the entire plasma cutting installation may be considered for special applications.

Position the power supply

Locate the Powermax45 near an appropriate 200–240volt power receptacle for CSA or CE 1-phase power supplies, a 400volt receptacle for 3-phase CE power supplies, or a 480volt receptacle for 3-phase CSA power supplies. The Powermax45 has a 3m (10-foot) power cord. Allow at least 0.25m (10inches) of space around the power supply for proper ventilation.

Prepare the electrical power

The maximum output voltage will vary based on your input voltage and the circuit’s amperage. Because the current draw varies during startup, slow-blow fuses are recommended as shown in the following chart. Slow-blow fuses can withstand currents up to 10times the rated value for short periods of time.
Voltage configurations
The following chart shows the maximum rated output for typical combinations of input voltage and amperage. Acceptable input voltages can be ±10% of the values given below.
CAUTION
Protect the circuit with appropriately sized time-delay (slow-blow) fuses and a line-disconnect switch.

Install a line-disconnect switch
Use a line-disconnect switch for each power supply so that the operator can turn off the incoming power quickly in an emergency. Locate the switch so that it is easily accessible to the operator. Installation must be performed by a licensed electrician according to national and local codes. The interrupt level of the switch must be equal to or exceed the continuous rating of the fuses. In addition, the switch should:
• Isolate the electrical equipment and disconnect all live conductors from the incoming supply voltage when in the OFF position.
• Have one OFF and one ON position that are clearly marked with O (OFF) and I (ON).
• Have an external operating handle that can be locked in the OFF position.
• Contain a power-operated mechanism that serves as an emergency stop.
• Have slow-blow fuses installed as recommended in the table on the previous page.
Requirements for grounding
To ensure personal safety, proper operation, and to reduce electromagnetic interference (EMI), the Powermax45 must be properly grounded:
• The power supply must be grounded through the power cord according to national and local electrical codes.
• Single-phase service must be of the 3-wire type with a green or green/yellow wire for the protective earth ground
and must comply with national and local requirements. Do not use a 2-wire service.
• Three-phase service must be of the 4-wire type with a green or green/yellow wire for the protective earth ground and must comply with national and local requirements.
• Refer to the Safety and Compliance Manual for more information.

Power cord considerations

Powermax45 power supplies are shipped with CSA and CE power cord configurations.
The power cords on the 200–240V CSA power supplies are shipped with a 50 amp, 250V plug (NEMA 6-50P) on the power cord.
The CE power supplies and the 480V CSA power supplies are shipped without a plug on the power cord. Obtain the correct plug for your unit (230V CE, 400V CE, or 480V CSA) and location and have it installed by a licensed electrician.

Prepare the gas supply

The gas supply for the Powermax45 can be shop-compressed or cylinder-compressed.A high-pressure regulator must be used on either type of supply and must be capable of delivering gas to the filter on the power supply at 170l/min at
6.2bar (360scfhat90psi).
WARNING
Do not allow the gas supply pressure to exceed 9.3 bar (135 psi). The filter bowl may explode if this pressure is exceeded.
If gas supply quality is poor, cut speeds decrease, cut quality deteriorates, cutting thickness capability decreases, and the life for consumables shortens. For optimum performance, the gas should have a maximum particle size of 0.1micron at a maximum concentration of 0.1mg/m3, a maximum dew point of -40°C (-40°F), and a maximum oil concentration of
0.1mg/m3 (per ISO8573-1 Class1.2.2).

Connect the gas supply
Connect the gas supply to the power supply using an inert gas hose with a 9.5mm (3/8 inch) internal diameter and a 1/4NPT quick-disconnect coupler or a 1/4NPTxG-1/4 BSPP (CE units) quick-disconnect coupler.
CAUTION
Synthetic lubricants containing esters that are used in some air compressors will damage polycarbonates used in the air regulator bowl.
5.5 – 6.9 bar (80 – 100 psi) gas supply (maximum 9.3 bar or 135 psi) with a flow rate of at least 165.2 l/min (350 scfh). The recommended flow rate and pressure is 170 l/min at 6.2 bar (360scfh at 90 psi).
Additional gas filtration
When site conditions introduce moisture, oil, or other contaminants into the gas line, use a three-stage coalescing filtration system, such as the Eliminizer filter kit (128647) available from Hypertherm distributors. A three-stage filtering system works as shown below toclean contaminants from the gas supply.
