The shield in the sensor module is isolated from the frame of the encoder for maximum noise
immunity. Connect the shield wire or pin to the shield of the cable and that of the drive or other
receiving device.
2.3.1 Quick Release Connector Hood Installation
1.
Remove the four screws from the mating connector housing that holds the terminal block in place. Remove terminal
block from housing.
2.
Insert wiring through liquid tight flexible seal and mating connector housing. Leave enough wire exposed to
comfortably reach the terminal block. Wire to terminal block according to wire code in Table 1. A similar wiring list is
attached to enclosure.
There are two orientations of the connector hood. The terminal block can be inserted with either
the connector hood up or down. Choose the best direction for your application.
4. Tighten Liquid Tight fitting on housing.
OPTIONAL
: In some hostile environments, seal between connector body and
Sensor Module can be improved by smearing a sealant (silicone grease, etc.) on the neoprene seal of the connector.
5.
Mate connector into place on sensor mount and snap the two latches into place. If only one sensor is being installed,
ensure cover plate is installed over other sensor hole.
