Safety information Product information Mechanical installation Electrical installation Multi axis system design Technical data6 Digitax HD M75X Series Installation and Technical GuideIssue Number: 51 Safety information1.1 Warnings, Cautions and NotesA Note contains information which helps to ensure correct operation ofthe product.1.2 Important safety information. Hazards.Competence of designers andinstallersThis guide applies to products which control electric motors eitherdirectly (drives) or indirectly (controllers, option modules and otherauxiliary equipment and accessories). In all cases the hazardsassociated with powerful electrical drives are present, and all safetyinformation relating to drives and associated equipment must beobserved.Specific warnings are given at the relevant places in this guide.Drives and controllers are intended as components for professionalincorporation into complete systems. If installed incorrectly they maypresent a safety hazard. The drive uses high voltages and currents,carries a high level of stored electrical energy, and is used to controlequipment which can cause injury. Close attention is required to theelectrical installation and the system design to avoid hazards either innormal operation or in the event of equipment malfunction. Systemdesign, installation, commissioning/start-up and maintenance must becarried out by personnel who have the necessary training andcompetence. They must read this safety information and this guidecarefully.1.3 ResponsibilityIt is the responsibility of the installer to ensure that the equipment isinstalled correctly with regard to all instructions given in this guide. Theymust give due consideration to the safety of the complete system, so asto avoid the risk of injury both in normal operation and in the event of afault or of reasonably foreseeable misuse.The manufacturer accepts no liability for any consequences resultingfrom inappropriate, negligent or incorrect installation of the equipment.1.4 Compliance with regulationsThe installer is responsible for complying with all relevant regulations,such as national wiring regulations, accident prevention regulations andelectromagnetic compatibility (EMC) regulations. Particular attentionmust be given to the cross-sectional areas of conductors, the selectionof fuses or other protection, and protective ground (earth) connections.This guide contains instructions for achieving compliance with specificEMC standards.All machinery to be supplied within the European Union in which thisproduct is used must comply with the following directives:2006/42/EC Safety of machinery.2014/30/EU: Electromagnetic Compatibility.1.5 Electrical hazardsThe voltages used in the drive can cause severe electrical shock and/orburns, and could be lethal. Extreme care is necessary at all times whenworking with or adjacent to the drive. Hazardous voltage may be presentin any of the following locations:• AC and DC supply cables and connections• Output cables and connections• Many internal parts of the drive, and external option unitsUnless otherwise indicated, control terminals are single insulated andmust not be touched.The supply must be disconnected by an approved electrical isolationdevice before gaining access to the electrical connections.The STOP and Safe Torque Off functions of the drive do not isolatedangerous voltages from the output of the drive or from any externaloption unit.The drive must be installed in accordance with the instructions given inthis guide. Failure to observe the instructions could result in a firehazard.1.6 Stored electrical chargeThe drive contains capacitors that remain charged to a potentially lethalvoltage after the AC supply has been disconnected. If the drive has beenenergized, the AC supply must be isolated at least ten minutes beforework may continue.1.7 Mechanical hazardsCareful consideration must be given to the functions of the drive orcontroller which might result in a hazard, either through their intendedbehaviour or through incorrect operation due to a fault. In any applicationwhere a malfunction of the drive or its control system could lead to orallow damage, loss or injury, a risk analysis must be carried out, andwhere necessary, further measures taken to reduce the risk - forexample, an over-speed protection device in case of failure of the speedcontrol, or a fail-safe mechanical brake in case of loss of motor braking.With the sole exception of the Safe Torque Off function, none of thedrive functions must be used to ensure safety of personnel, i.e.they must not be used for safety-related functions.The Safe Torque Off function may be used in a safety-relatedapplication. The system designer is responsible for ensuring that thecomplete system is safe and designed correctly according to therelevant safety standards.The design of safety-related control systems must only be done bypersonnel with the required training and experience. The Safe TorqueOff function will only ensure the safety of a machine if it is correctlyincorporated into a complete safety system. The system must be subjectto a risk assessment to confirm that the residual risk of an unsafe eventis at an acceptable level for the application.1.8 Access to equipmentAccess must be restricted to authorized personnel only. Safetyregulations which apply at the place of use must be complied with.1.9 Environmental limitsInstructions in this guide regarding transport, storage, installation anduse of the equipment must be complied with, including the specifiedenvironmental limits. This includes temperature, humidity,contamination, shock and vibration. Drives must not be subjected toexcessive physical force.1.10 Hazardous environmentsThe equipment must not be installed in a hazardous environment (i.e. apotentially explosive environment).A Warning contains information which is essential foravoiding a safety hazard.A Caution contains information which is necessary foravoiding a risk of damage to the product or other equipment.WARNINGCAUTIONNOTE
