Aegis Shaft Grounding Brush Split Ring Installation Guide for NEMA Motors

SGR Installation Instructions

AEGIS^® Bearing Protection Ring for NEMA & IEC Motors Installation Instructions

Installation Guide:

Shaft must be clean & free of any coatings, paint, or other nonconductive material. Lightly sand shaft to remove any oxide coating.
SGR should not operate or come in contact with the keyway during operation. If necessary, adjust or change spacer and screw lengths..
Remove mounting brackets from the bottom half of the AEGIS^® Bearing Protection Ring. See above.
Reassemble the AEGIS^® ring around the motor shaft. Maintain an even clearance around the shaft. Conductive MicroFibers™ must be in contact with conductive metal surface of the shaft.
Mark your drill points on the end bell through the slots in the plate. Slide kit away from the end bell to drill holes.
- English Mounting Hardware:
  1. Drill (3) holes using a #29 drill
  2. Depth of hole should be 1/4 max*
  3. Tap each hole with a #8-32 tap
- Metric Mounting Hardware:
  1. Drill (2) holes using a 3.3mm drill
  2. Depth of hole should be 6mm *
  3. Tap each hole with a M4 x 0.7 tap
Secure the kit in place with screws, washers and spacers provided. Final location of SGR fibers should not be located over keyway. Proper operation and grounding of the SGR is reliant on the mounting screws to the motor housing. Alternate hardware used for mounting should be conductive. Do not use Locktite or any other non-conductive material to secure the screws. Consult EST with any questions.
After installation, test for conductive path to ground using Ohm meter. One probe on metal frame of SGR and one probe on motor frame. NOTE: Motor grounding must be in accordance with applicable wiring standards.
CAUTION: SGR IS NOT
A GROUND FAULT
PROTECTION DEVICE.
In occasions where SGR is exposed to excessive debris, additional protection of the SGR fibers may be necessary. Call technical support at 207-998-5140 or email techsupport@est-aegis.com
