Installation Notes:

  • The up arrow should not point below horizontal.
  • Do not solder to or bend terminals.
  • Avoid lateral forces and mechanical loads (overly stiff or tight wires).
  • Do not rigid mount both ends of the Mercotac.
  • Limit the mounting eccentricity (runout / wobble) to .005" (.13mm).
  • Provide overload protection within the circuit.
  • Avoid vibration and bumping motions.
