To use the encoder in a hazardous area, a safety barrier or galvanic isolator has to be used.  Our six channel barrier and isolator work with our encoders.  Isolator Data Sheet

Mounting Instructions

Slide encoder onto shaft.  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.
