Mounting Instructions
Thread the encoder shaft onto the matching threaded shaft and tighten both ends.  Add a bit of copper slip for it not to seize up.  To keep encoder from rotating: have a pin to prevent rotation in one of the mounting holes, or a bracket bolted onto the mounting holes, or simply tie wrap the cable.  Whatever is done, ensure there is a bit of play between encoder and mounting arrangement to prevent bearing damage.  Hook up the encoder with the connections as described.  Make sure power supply meets specifications.
