Bosch Rexroth IndraDyn S - MKE Project Planning Manual

Project Planning Manual | Rexroth MKE Synchronous Motors Electric Drivesand Controls| Bosch Rexroth AG 101/131InstallationDANGERWARNINGWARNINGDanger to life and limb due to electrical power! Handling within the rangeof live parts is extremely dangerous. Therefore:●●●Any work required on the electric system may be carried out only by skilledelectricians. It is absolutely necessary to use power tools.Before starting work, the system must be de-energized and the powerswitch be secured against unintentional or unauthorized re-energization.Before starting work, the appropriate measuring equipment must be usedto check whether parts of the system are still applied to residual voltage(e.g. caused by capacitors, etc.). If yes, wait until these parts have discharged.Injuries to persons or property possible! Interrupting or connecting livelines may cause unpredictable dangerous situations or lead to physicaldamage. Therefore:●●Connect and disconnect plug connectors only when they are dry and deenergized.During operation of the system, all plug connectors must be securelytightened.Risk of short-circuit caused by liquid coolant or lubricant! Short-circuitsof live lines may cause unpredictable dangerous situations or lead tophysical damage. Therefore:●Provide open mating sides of power plug connectors with safety capswhen installing or replacing drive components if you cannot exclude thatthey might be moistened with liquid coolant or lubricant.11.4.2 Motor Connection according to European Standard (EN)MKE037, -047, -098WARNINGDamages to the terminal box or the cable are possible!Too high tightening torques can damage the bolt-on fixing or can squeeze thecable. If bolt-on fixings are damaged, the protection IP65 on the terminal boxcannot be ensured any longer.●In fact of this use no automatic screwdriver (e.g. electronical, pneumaticor hydraulic screwdriver).MKE motors in EU design are equipped with terminal boxes that are optimisedfor the storage of ready-made Rexroth cables.In case of MKE motors, ignition cleavages are a positive Ex protectionmeasure. Perfect compliance with the ignition cleavage tolerances ensuresthat, under a fault condition, ignition sparks cannot leave the motor's innerchamber to the outside. The terminal box cover forms an ignition cleavage withthe motor housing which has to be opened and closed again during assemblyand disassembly of the terminal box cover. Work carefully! Replace damagedterminal box covers.Mount the ready-made cables in the following order:
