2. Electrical installation
Turno󰓐themachinebeforebeginninganycleaning,maintenanceorrepair
procedure.Alwaysswitchthemachineo󰓐beforeconnectingordisconnectinga
cable or optional accessory.
Never unplug a cable while the machine is turned on (except for the mains lead in the
event of an emergency). The power outlet must be located alongside the equipment
and must be easily accessible.
Do not remove the power supply cover: risk of electric shock. The connection to
the single phase power supply is made with a standard, 3 pin plug with grounding.
Groundingmustbedoneaccordingtotheregulationsine󰓐ecttoensurethesafetyof
the personnel.
To avoid interference problems due to the external environment, observe the following:
• Usethelinkcablessupplied.TheycomplywithEMCradio-frequencyinterferenceemissionstandardsand
provideprotectionfromexternalelectricalinterference(compliantwithEMCimmunityandsusceptibility
standards).
• Bringtheitemsofequipmenttobelinkedasclosetogetheraspossibletoreducethelengthofcabletobe
used.
• Separatethepowercablefromthelinkcableandmakesurethepowerandlinkcablesdonotrunthrough
the same cable tray.
• Connect the machine direct to a mains power line and avoid connecting more than one device to that line
(bypluggingseveraldevicesintothesamemainssocketorintoamulti-wayadapter).
• Do not allow inductive or capacitive devices to be connected to the same mains power line as the machine
(motors,solenoidvalves,chargers,etc.).
• Avoid the installation of manual or automatic switching systems on the same mains power line as the
machine(relays,timers,programmers,automaticcircuit-breakers,automaticswitches,etc.).
• Checkthat devices in the vicinity of the machine meet the standards for electromagnetic interference.
Read the technical data sheet for each device. If they are non-compliant, move them as far away from the
machine as possible.
• Connections and cabling: separate the power supply cables from the control cables in cable ducts and in
thecabinet(forcontrolcables,asectionof0.34mm²isrecommended).
• Equipment󰘰ltering:therelaysconnectedtothemarkingmachineshouldincludeadeviceforsuppressing
interferenceontheoperatingcoil(freewheelingdiodeforDCrelaysorRCcircuitforACrelays).
• Connection of shielding: the communication cables (All Or Nothing I/O or Ethernet - RS232 computer
cables) must be shielded with both ends of the shielding connected to the equipment ground via the
shortestpossiblelink.
• Grounding:connecttogetheralltheconductivemetalgrounds(nopaintortreatmentsuchasanodization)
oftheequipment(frame,cabinet,markingmachine)toensuree󰘯ectiveconnection.Wherepossible,there
should be multiple connection points to improve the connection quality.
• Use the Gravotech accessories.
