The followingapplies for the shaft groundingdevice: If no digital speedencoder is used (standard),it is mounted in a separateenclosure (no code is requiredwhen ordering). When a digitalspeed encoder is used, itis integrated there (code fordigital speed encoder H76,refer to section 4).¦ In order to effectively protectthe bearings of the drivenload, we recommend thatinsulated couplings are used.The rubber-elastic couplingsused in most applications arealready isolated. For almostall other applications, insulatedcouplings are availableas standard from couplingmanufacturers.¦ The rated frequency of themotor must be at least 20 Hz.For the H-compact andH-compact PLUS high-voltagemotors, the technical data forthe following main applicationsis specified in section 4¦ drives with square-law loadtorque, and¦ constant-load torque drives.The data is valid for a coolingmediumtemperature of 25 °C(water) or 40 °C (air), an installationaltitude up to 1000 m aswell as utilization in accordancewith temperature rise class F.For other conditions, the factorsspecified in the tables onPages 4/4 and 4/38 must betaken into account. If themotors may only be utilized inaccordance with temperaturerise Class B, then they must bede-rated down to 88%.6Motors 2 x 4.16 kVFor increased output of theSIMOVERT MV drive converters,it is possible to connecttwo input rectifiers and two invertersin parallel. In so doing, amaximum output current of upto 9.1 MVA at an output voltageof 4.16 kV can be achieved.In order to ensure balancedcurrent between the two partialsystems, the motor requirestwo electrically isolated windingsystems which have no electricalphase offset (Fig. 6/9).Separate winding systems areavailable for the high-voltagemotors H-compact PLUS. Nooutput filter is required for thesemotors.With option L08 (output reactor)a motor with only one windingsystem can also be used.DC linkSystem BPhaseunitsInverterFig. 6/9Parallel connection: inverter side with two winding systems in the motorSystem AMotor6/12 Siemens DA 63 · 2004
