Installation: See Figure 1 for illustrated assembly.
1. Place securing ring and/or adjusting nut as supplied on unit and thread unit into panel until bushing extends
approximately 11/32" (8.7) [4 to 5 threads], past front of panel - 9/32" (7.1) [3 to 4 threads] if a legend plate is
not to be used, see Figure 3.
2. To secure unit, rotate to a position which provides electrical clearance and tighten adjusting nut and/or locking
screw. Where two units are mounted adjacently, arrange securing rings to avoid interference.
3.
When Installing in a metal enclosure, maintain 1/2” (12.7) minimum
WARNING
clearance through air between current carrying parts enclosure.
4. Place legend plate, if to be used, over mounting bushing.
5. Assemble mounting ring adapter and tighten.
6. Rotate shaft counterclockwise to stop.
7. Position knob on shaft aligning white indexer on knob with "min." increment marking on legend plate.
8. Tighten the two set screws in the knob to 4 ± ½ lb.-in. with a 1/16" (1.6) hex wrench.
9. Install mounting ring and tighten. Allen-Bradley Catalog No. 800T-N3 wrench is available for this operation.
Replacing Potentiometer: See Figure 3 for illustrated assembly.
NOTE 1: Refer to nameplate on housing for original potentiometer resistance.
NOTE 2: Unit need not be removed from enclosure to replace potentiometer.Potentiometer Removal:
1. Remove the two screws on the rear of the housing and pull the housing (see Figure 3) from the bushing.
2. Disconnect the three wire leads from the potentiometer terminals.
3. Loosen the two set screws in the shaft adapter with a 1/16" (1.6) hex wrench and remove shaft adapter from
potentiometer shaft.
4. Remove nut, lockwasher and mounting plate.
Potentiometer Installation:
1. Remove mounting ring leaving mounting ring adapter in place. Allen-Bradley Catalog No. 800T-N3 wrench is
available for this operation.
2. Loosen the two set screws in the knob with a 1/16" (1.6) hex wrench and remove knob.
3. Rotate shaft so that it extends .40 ± .01 (10.2 ± .2) from bushing.
4. Before installing potentiometer bend the three terminals 80° -90° and remove nut and lockwasher from
bushing (see Figure 2).
5. Install mounting plate, printed side facing outward, over potentiometer shaft aligning locating tab on
potentiometer with slot in mounting plate.
6. Tighten nut and lockwasher on potentiometer shaft and bend locating tab to fit mounting plate.
7. Insert wire leads onto the potentiometer terminals making sure the leads identified as 1, 2 and 3 are attached
to the correspondingly identified potentiometer terminals. (See Figure 3 for terminal identification.) If the
potentiometer housing does not have wires with terminal lugs, cut and strip the wires and solder the wire end
to the appropriate potentiometer terminal.

8. Rotate potentiometer clockwise to stop.
9. Place shaft adapter onto potentiometer shaft. Rotate shaft adapter to orient slot in shaft adapter with roll pin
in shaft while holes in diaphragm and mounting plate are in line with holes in mounting bushing.
10. Tighten the two set screws in the shaft adapter to 4 ± ½ lb.-in. with a 1/16" (1.6) hex wrench.
11. Line up holes in housing, mounting plate, and mounting bushing and push the unit into the mounting
bushing.
12. Secure by threading in the two screws from the rear of the potentiometer housing.
13. Rotate shaft counterclockwise to stop.
14. Position knob on shaft aligning white indexer on knob with "min." increment marking on legend plate.
15. Tighten the two set screws in the knob to 4 ± ½ lb.-in. with a 1/16" (1.6) hex wrench.
16. Install mounting ring and tighten. Allen-Bradley Catalog No. 800T-N3 wrench is available for this operation.
Enclosure must comply with U.L. standards 698 and 1203 and CSA standard C22.2 No. 30 for Class I
Groups B, C and D hazardous locations or C22.2 No. 25 for Class II Groups E, F and G hazardous locations.
For Class I locations, a suitable seal fitting is required within 18 inches.
