Procedure
Follow the procedure below to mount the AC191 Terminal Block on the bearing shoe. This procedure is adaptable to other types
of bearings and to equipment other than bearings.
Step
1 Drill or counterbore a 0.625" ± .005" (15,9 mm ±13 mm) diameter hole, .1875" deep, in the bearing shoe at the desired
location. The terminal block may be located adjacent to the detector leadwire hole, and must be mounted within the
leadwire length of the detector being installed.
2 Insert the terminal block in the 0.625" (15,9 mm) diameter hole with the leadwire grooves aligned with the direction
the leadwires will lay.
3 Peen over the metal of the shoe into the recess in each quadrant of the terminal block to hold the terminal block
securely in place.
4 Form the stripped and tinned ends of the detector leadwires into the solder cups of the terminal block. Do the same
with the leadwires exiting the terminal block. Solder the leadwires into the solder cups with 60/40 alloy solder (for use
to 360°F (182°C)) or higher temperature solder if service conditions require.
5 Lay the leadwires flat in the bottom of the milled groove in the bearing shoe. Pot the leadwires in the groove using an
epoxy or other potting compound compatible with the bearing shoe material, temperature and service conditions..
