3.2.1.2 Hard-wiring the Digital Gateway to the sc100

Important Note: Hard-wiring the digital gateway to the sc100 is not an approved method 
for Class 1, Division 2 Hazardous Locations. 

1.

Disconnect power to the controller if powered. 

2.

Open the controller cover. 

3.

Disconnect and remove the existing wires between the quick-connect and terminal 
strip J5, see 

Figure 8 on page 15

4.

Remove the quick-connect fitting and wires and install the threaded plug on the 
opening to maintain the environmental rating.

5.

Cut the connector from the sensor cable. 

6.

Strip the insulation on the cable back 1-inch. Strip ¼-inch of each individual wire end.

Note: Use of strain relief fitting other than Cat. No. 16664 may result in a hazard. Use only the 
recommended strain relief fitting. 

7.

Pass the cable through conduit and a conduit hub or a strain relief fitting (Cat. No. 
16664) and an available access hole in the controller enclosure. Tighten the fitting. 

8.

Reinstall the plug on the sensor access opening to maintain the environmental rating.
