Edge Connectors
The XT main control circuit boards have PolySi PST-576 dielectric grease applied to the edge connectors.
If necessary, an edge connector grease applicator kit, catalog number SK-RM-GRAPP1, is available to re-apply grease to edge connectors on circuit boards.
IMPORTANT:
When handling circuit boards with grease:
  • Do not touch or remove the grease
  • Do not allow the grease to become contaminated
