Installation

Mechanical

This chapter describes how to install the 842E EtherNet/IP Encoder.

Also refer to the installation sheet provided in the box, Publication No.

100000169360.

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.

2. Use the dimension drawings in the installation instructions to determine

the encoder mounting hole locations (see “Related documentation” on

page iii).

3. Slide the flexible coupling onto the shaft, but do not tighten the set screws.

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.
