Mounting Instructions
IMPORTANT: Be sure mating shaft is chamfered and
grease-free.
1. Loosen the screw on the clamping ring with a 3/32 inch
hexagon socket wrench.
2. Slide the encoder onto the mating shaft until the tether
mount or anti-rotation pin rests on the machine surface.
The encoder should slide freely on the shaft; if not, do not
force. Check the shaft for interferences such as gouges,
burrs, rust or size.
If a mounting hole or anti-rotation pin stop already exists,
proceed to step 6.
3. Mark the mounting hole and/or anti-rotation pin stop
location.
4. Slide the encoder off. Drill and tap the marked hole to
accept the 0.375 inch x 16 (tether option B or C) or 0.5
inch x 13 (tether option A) bolt.
5. Slide the encoder back in the shaft until the tether mount
or anti-rotation pin rests on the machine surface.
6. Attach the encoder with either the 0.375 inch or 0.5 inch
bolt.
IMPORTANT: Do not stress the tether mount while
tightening the bolt.
7. Tighten the clamping ring to 8 inch-lbs.
8. Make the electrical connections according to the table
under “Electrical Connections.”
IMPORTANT: Wiring must be in accordance with the
National Electric Code and applicable local codes and
ordinances.
9. Apply the specified voltage (see Table “e” under
“Selection” on page 1 of this publication).
