IMPORTANT: Make sure that the module is level and goes into the encoder smoothly without
binding or scraping other modules. The module should slide easily until you feel the module engage

the module.
2. Secure the module to the chassis using a Phillips-head screwdriver, as shown in step 2,
Figure 5–11 .
