Wiring the GD-K8A4X to a Controller
WARNING: Always verify that power to the GD-K8A4X and to the controller are off
and that the controller’s power switch is in the off position before making
wiring connections or adjustments.
1.
Turn off power to the controller.
2.
Place the controller’s power switch in the OFF position.
3.
Use the conduit hub at the bottom of the GD-K8A4X for routing shielded cable into
the enclosure. See Figure 1 for the wiring connections.
4.
Connect the cable shield’s drain wire to a chassis ground at the controller, but do not
connect it at the GD-K8A4X.
CAUTION:

You will connect the opposite end of the cable shield’s drain wire at the controller.
CAUTION:
At the controller, do not route power and GD-K8A4X wiring through the same
conduit hub. The power cable may disrupt the transmission of the GD-K8A4X’s
signal to the controller.
