3.2.2.1 Attaching the Digital Gateway with a Quick-Connect Fitting in a Hazardous Location

The digital gateway is supplied with a keyed quick-connect fitting for easy attachment to the controller, see Figure 7 on page 14. For Hazardous Locations, a connector safety lock (Cat. No. 6139900) must be installed. Retain the connector cap to seal the connector opening in case the sensor must be removed.

1.Remove the connector cap from the sc100 controller. Retain the connector cap to seal the connector opening in case the sensor must be removed.

2.Connect the digital gateway connector to the sensor plug on the sc100.

3.Install the connector safety lock (Figure 9). Align the lock over the connector and squeeze the two halves together to lock. To remove the connector safety lock, insert a small flat-blade screwdriver into the locking groove. Pivot the screwdriver away from the groove and separate the two halves (Figure 9).
