Project Planning Manual | Rexroth MKE Synchronous Motors Electric Drivesand Controls| Bosch Rexroth AG 105/131InstallationThe explosion protection for the cable entries can only be guaranteed,when they are in their original condition. The explosion protectioncan no longer be guaranteed, if:●●●the isolator is damaged, broken or flaking.the winding of the screw-grommet is damaged.the cleavage face of the assembling bolt was changed, processedod damaged.The servicing and repair of MKE motors must only be carried outby certified Rexroth service employees.Grommets must be used at mounting, which are adjusted with the cable outerdiameter in which the threads must be applied.ScrewingAvailable grommets with nominal diameter Tolerance-0.5 mmLE20/9(Encoder)LE26/15(Power 2.5 mm²)LE26/19(Power 6.0 mm²)8,5 9,0 9,513,5 14,0 14,5 15,0 15,5 16,0 16,517,5 18,0 18,5 19,0 19,5Fig.11-5:Grommets for Ex cable fittingsDANGERDanger of explosion, danger to life, heavy injury and material damage⇒ Only cable fittings mounted according to the rules prevent the penetration ofpotentially explosive gases / dusts.⇒ Make sure that only grommets are used, which are adjusted to the cablediameter.The following steps are necessary:1. Determine the outer diameter of the cable on the clamping of the cablefitting.Fig.11-6: Determine the cable's diameter2. Select the necessary grommet and mount it on the cable fitting.3. Tighten the cable fitting as far as it will go.The cable fittings are mounted according to the Ex regulations.Mount and connect ready-made cablesReady-made cables are mounted according to Fig. 11-7.
