4.0 Sensor Module Installation
To install the Sensor Module, perform the following steps. See Figure 15.
Remove sensor module and mating connector from packaging.
Although the device is protected from Electrostatic Discharges up to 2000 Volts, standard ESD precautions
should be followed.
Separate mating connector from sensor module by releasing the two latches.
Use caution when handling the sensor module. The sensor at the end of the module can be easily damaged
by sharp objects. The sensor module can be damaged by sudden shocks (dropping, hammer blows, etc.).
Insert sensor module into opening in enclosure. The sensor assembly is keyed to ensure proper orientation (blue side goes
toward motor facing).
Locate four socket head cap screws. Insert socket head cap screws through clearance holes in sensor module and into tapped
holes in enclosure. Tighten to a nominal 5 inch-pounds.
There should not be a gap between the lip on the housing and the enclosure. The stainless steel sensor
module is designed to seat in metal-to-metal contact with the enclosure. Ensure that no gaskets, paint, dirt, etc.,
interferes with the complete seating of the module in the enclosure.
