Installation
Mechanical This chapter describes how to install the 842E-CM integrated motion
encoder on EtherNet/IP.

publication No.
842E-IN002 (10000481742).
Shaft Rotation Direction
When you view the encoder from the shaft side, the shaft rotation is
clockwise (CW) or counterclockwise (CCW), as shown.
Mounting with a Solid Shaft
1. Be sure to select the proper size flexible coupling clamp to mate to
the encoder shaft, e.g., 845–FC–*–*. See encoder accessories in the
Sensors catalog (C116-CA001).
ATTENTION: Do not rigidly connect the encoder shaft to the machine; this will
cause premature failure of the encoder or machine bearings. Always use a
flexible coupling.
