5. Connect the signal line to the customer terminal strip. You will find details of this in the circuit
manual.
6. Connect the shield of the encoder cable directly to the shielding bus (serrated bar). It is
important here to establish the greatest possible area of contact and a good conductive
connection. Use metal ground clamps to secure the shield in place.
Connection example: HTL encoder, bipolar, with reference signal
This example shows the connection assignment on the sensor module. The terminals of the
sensor module are wired to the customer terminal strip. For further information, see the circuit
manual.

Figure 6-9 Connection example: HTL encoder, bipolar, with reference signal
Use a bipolar connection. The unipolar connection should only be employed when the encoder
type being used does not provide push-pull signals.
