2. Place the controller’s and GD-K7D24X’s power switches in the OFF position.
3. Use the conduit hubs at the bottom of the GD-K7D24X for routing shielded cable into
the enclosure and then route the cable through the cable bushing on the GD-K7D2.
See the Installation sections of the GD-K7D2 Operator’s Manual for wiring
connections between the GD-K7D2 and the controller.
Two conduit hubs are provided on the enclosure. One of them may be used for AC
power if a 115 VAC GD-K7D2 is installed. Plug any unused conduit hub with a 3/4”
conduit plug.
4. Connect the cable shield’s drain wire to a chassis ground at the controller, but do not
connected it at the GD-K7D24X.
CAUTION: Leave the cable shield’s drain wire insulated and disconnected at the GD-K7D24X.
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-K7D24X wiring through the same
conduit hub. The power cable may disrupt the transmission of the GD-K7D2’s
signal to the controller.
Start Up
See the GD-K7D2 Operator’s Manual for GD-K7D2 startup instructions.
Operation
See the GD-K7D2 Operator’s Manual for an operational description of the GD-K7D2 that

Maintenance/Calibration
See the GD-K7D2 Operator’s Manual for maintenance and calibration instructions. Use
the inlet fitting on the NEMA 4X enclosure to apply gas instead of the fittings inside the
