If necessary, these Yellowcards can be requested from the responsible sales office.Within potentially explosive areas, MKE motors must only be usedin connection with the drive devices of Bosch Rexroth AG.Potentially explosive areaWhen mounting the drive control devices in potentially explosive, the followingcomponents must fulfill the Ex protection requirements:●●Motor with attached partsCircuits leading into the potentially explosive areaUse in Class I(1) Potentially explosive area with explosion-protected equipments(2) Control cabinet(3) Drive control device(4) MKE motor(5) Connections (optional)(6) Connection cables in a steel pipe(7) Ex terminal box (not included in scope of delivery)Fig.9-7: Potentially explosive areaThe MKE motors described in this documentation are UL listed and may beused in hazardous areas according to Class I, Groups C and D.The related drive control devices and connections of the connection cables(power and feedback connection) must be outside of the hazardous area.
Project Planning Manual | Rexroth MKE Synchronous Motors Electric Drivesand Controls| Bosch Rexroth AG 81/131Operating Conditions and Application NotesDANGERDanger of explosion, danger to life, heavy injury and material damage⇒ Do not set up drive control devices or connectors in potentially explosiveareas.⇒ Make sure that connectors cannot reach into the hazardous areas.⇒ Do not disconnect the connections under load!⇒ Make sure that no ignition sparks could occur within the hazardous area.9.2 Setup Height and Ambient TemperatureNominal dataExceeding the nominal data Derating– curvesThe performance data specified for the motors apply under the following conditions:● Ambient temperatures of 0 to +40 ºC●Setup heights of 0 to 1000 m above MSL.If you intend to use motors above these ranges, you must take the “utilizationfactors” into consideration. This reduces the performance data.9.3 Degree of Protection(1) Utilization depending on the ambient temperature(2) Utilization depending on the setup elevationf TTemperature utilization factort AAmbient temperature in degrees CelsiusΔT60 Operating modef HHeight utilization factorhSetup height in metersFig.9-8: MKE derating (utilization factors)If either the ambient temperature or the setup height exceeds the nominal data:1. Multiply the torque data specified in the selection data by the utilizationfactor.2. Ensure that the reduced torque data are not exceeded by your application.If both the ambient temperature and the setup height are exceeding the nominaldata:1. Multiply the load factors f T and f H determined.2. Multiply the value obtained by the motor torque data specified in the selectiondata.3. Ensure that the reduced torque data are not exceeded by your application.The degree of protection is defined by the abbreviation IP (International Protection)and two reference numbers specifying the degree of protection.
