Grounding:
For applications with high ground potential differences, DO NOT ground the encoder through
both machine and controls end. Connect the shield at the controls end only.
NOTE: If the shield is
connected at both ends,
grounding problems that degrade system performance can result.
CE Grounding Measures
– For best EMC immunity the cable screen must be grounded on both encoder and
controls end. For cable lengths longer than 30m or outdoor applications, additional measures must be
implemented to comply with CE requirements. Connection of the encoder to DC power supply network is
prohibited if CE compliance is required. CE-compliant products are tested to EN61326-1 EMC.
In all cases, system CE compliance is ultimately the responsibility of the manufacturer integrating the encoder.

NOTE
The shield in the sensor module is isolated from the frame of the encoder. For maximum
noise immunity, the shield wire or pin should be connected to the shield of the cable and
that of the drive or other receiving device.
2.3.1 Quick Release Connector Hood Wiring
To install the Quick Release Connector, perform the following steps.
2.
Remove the four screws from the mating connector housing that hold the terminal block in place. Remove terminal
block from housing.
3.
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.
NOTE
There are two orientations of the connector hood. The terminal block can be
inserted either way so the connector hood points up or down. Choose the direction
best 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.
