COMBIMASTER & MICROMASTER Integrated8.4 COMBIMASTER INSTALLATIONWARNINGTo guarantee the safe operation of theequipment it must be installed andcommissioned by qualified personnel only.Take particular note of the general and regionalinstallation and safety regulations regardingwork on high voltage installations (e.g. VDE), aswell as the relevant regulations regarding thecorrect use of tools and personal protectivegear.Use the lifting eyes provided if the motor has tobe lifted. Do not lift machine sets (e.g. built-ongearboxes, fan units) by suspending theindividual machines!Always check the capacity of the hoist beforelifting any equipment.Wiring Guidelines to Minimise the Effects of EMIThe COMBIMASTER is designed to operate in an industrialenvironment where a high level of ElectromagneticInterference (EMI) can be expected. Usually, goodinstallation practices will ensure safe and trouble freeoperation. However, if problems are encountered, thefollowing guidelines may prove useful. In particular,grounding of the system 0V at the inverter, as describedbelow, may prove effective.(1) Ensure that all equipment is well earthed using short,thick earthing cable connected to a common starpoint or bus bar. It is particularly important that anycontrol equipment that is connected to the inverter(such as a PLC) is connected to the same earth orstar point as the inverter via a short, thick link. Flatconductors (e.g. metal brackets) are preferred asthey have lower impedance at high frequencies.(2) Wherever possible, use screened leads forconnections to the control circuitry. Terminate theends of the cable neatly, ensuring that unscreenedwires are not left visible.8.4.1 Mechanical InstallationFigures 1-7 show dimensional information for allCOMBIMASTER variants.Note:‘Case size’ refers to the type of inverter housing mounted onthe motor. ‘Motor frame’ refers to the motor frame size only.Remove or tighten down screw-in lifting eyes prior to usingthe COMBIMASTER.Stable foundations or mounting conditions, exact alignmentof the motors and a well-balanced transmission element areessential for quiet, vibration-free running. If necessary, insertshims under the motor's feet to prevent strain, or balance thewhole rotor and transmission element.Always use the correct tools for fitting and removingtransmission elements (coupling halves, pulleys, pinions,etc.).The rotors are dynamically balanced with the full featherkeyinserted as standard. Since 1991 the type of balance hasbeen marked on the drive end of the shaft (shaft end face).F denotes balanced with full featherkey; H denotesbalanced with half featherkey. Bear in mind the type ofbalance used when fitting the transmission element.Poor running characteristics can arise in cases where thetransmission elements have a length ratio of hub length tolength of shaft end < 0.8 and they run at speeds of > 1500rpm. In such cases rebalancing may be necessary, e.g. byreducing the distance by which the featherkey protrudesfrom the transmission element and the shaft surface.WARNINGTake suitable precautions to preventtransmission elements from being touched. Ifthe COMBIMASTER is started up without atransmission element attached, the featherkeymust be secured in position to prevent it fromflying off while the shaft is rotating.(3) Separate the control cables from the powerconnections as much as possible, using separatetrunking, etc. If control and power cables cross,arrange the cables so that they cross at 90° ifpossible.(4) Ensure that contactors in the cubicle are suppressed,either with R-C suppressers for AC contactors or‘flywheel’ diodes for DC contactors, fitted to thecoils. Varistor suppressers are also effective. This isparticularly important if the contactors are controlledfrom the relay connection on the COMBIMASTER.(5) Use screened or armoured cables for the powerconnections and ground the screen at both ends viathe cable glands.On no account must safety regulations be compromisedwhen installing the COMBIMASTER!Siemens DA 64 – 1998/99 8/7
