MOUNTING TO A NEMA 4.5" OR 8.5 C-FACE MOTOR WITH ROD TETHER
MODIFIED 1/2-13 X 1" FOR 8.5" C-FACE
MODIFIED 3/8-16 X 3/4" FOR 4.5" C-FACE
10-32 X 4" THREADED ROD
10-32 X 2.5" THREADED ROD
(CUT TO LENGTH AS REQUIRED)
2X 10-32 STUDDED ROD END
2X 10-32 SQUARE NUT
1. Assemble rod end turnbuckle assembly per image above.
2. Locate rod end mounting hole on the HT55, mount rod end assembly to one of four holes on the HT55. Tighten to 40 in-lbs.
3. Insert the appropriate bolt (3/8"-16 UNC or ½"-13 UNC pending on C-Face size) into one of four threaded holes on motor C-Face. Tighten
3/8"-16 UNC to 200 in-lbs. Tighten 1/2"-13 UNC to 500 in-lbs.
4. Slide the HT55 over the motor shaft. After positioning the encoder to the best angular orientation, adjust rod arm length, (thread rod may be
cut to length if necessary, for proper fit). While installing the encoder, engage the remaining end of the torque arm to the mounting bolt. Tighten
to 40 in-lbs.
5. Attach the remaining end of the anti-rotation arm to the mounting bolt. Add a removable threaded locker and tighten the turnbuckle locking
nuts.
6. Without the encoder being completely tightened, set the axial alignment so that no part of the torque arm assembly touches the motor, but is
perpendicular to the encoder body. Position should be as close to C-face as possible but not flush with motor.
7. Tighten clamp screws holding the encoder on the shaft with the hex wrench provided.
NOTE: Verify installation by checking clearance between the torque arm assembly and motor C-face.
NOTE: Verify installation by checking clearance between the torque arm assembly and motor C-face. The minimum motor shaft length
required should be approximately 1.6".
