Electrical Slip RingsInstallation & MountingPREPARATION:Remove the slip ring from the shipping container. Inspectthe entire assembly, including wire leads to make surethere is no visual damage that occurred during transport.RECOMMENDED INSTALLATION PRACTICE:Because of possible geometric mismatching between thecustomer’s application and the slip ring, “hard mounting”of both ends of the slip ring (i.e., securing the rotor andstator such that there is NO floating during operation) is notrecommended and may cause premature failure.THESE INSTRUCTIONS ARE INTENDED TO BE USED AS A GENERALGUIDE, PLEASE CONSULT DSTI TO DISCUSS ANY SPECIFICQUESTIONS RELATED TO YOUR INSTALLATION.INITIAL START-UP:Begin rotation of the equipment and verify that whilerotating at the maximum operating speed there is no visiblemovement of the slip ring assembly due to misalignmentand no binding or rubbing of the wire leads.MOUNTING EXAMPLECAPSULE SLIP RING, FLANGE MOUNT:The slip ring capsule is designed to be flange-mounted tothe customer’s interface while allowing either the barreland flange to be rotated or the rotor itself. The rotor leadscan be used to rotate with the equipment. Wrap the rotorand rotor leads together with heat shrink tubing for addedprotection.12Use screws to mount the slip ring. Washers can be usedprotect the flange from excessive strain. If lock washers arealso used, flat washers should be mounted between thelock washers and the flange. (Note: mounting hardware isnot included).The slip ring is not designed to bear the weight of theequipment to which it is connected. Rotating equipmentshould be secured so that no axial or radial load is appliedto the slip ring rotor.Secure all leads so that they do not rub against any surfaceas the equipment rotates. Care should be taken whenrouting and securing the leads so that no side loading ofthe slip ring occurs.31 BARREL & FLANGE (STATOR)2 ROTOR3 CUSTOMER INTERFACE EXAMPLEThe slip ring should be protected from dust and moisture.DSTI offers an optional IP65 Slip Ring Protective Enclosure(SRPE) for the ultimate protection against water, dust anddamage.5 Electrical Slip RingsDynamic Sealing Technologies, Inc phone 866.700.3784 web www.dsti.com store store.dsti.com
