3.3ENCLOSURE INSTALLATION

To protect the transmitter and sensor assembly they should be removed from the enclosure and preserved until final installation and wiring termination.

Prior to installation and wiring.

1.Remove the transmitter from the module housing by:

•Unscrew the two captive panel screws on the face plate.

3.4TRANSMITTER AND SENSOR INSTALLATION When all pre-wire is complete:

1.Install sensor assembly in the open hub on the module enclosure. The sensor assembly thread must be fully seated into the hub and tightened to maintain explosion proof assembly.

2.Connect the wires which return to the controller to transmitter connectors P1 and P2 (Figure 3-2) according to Figures 3-3 (Analog Output), 3-4 (Digital Interface), 3-5 (Remote Alarm Reset).

3.Connect the sensor assembly cable to transmitter connector J2.

4.Reconnect any required auxiliary wiring to the applicable terminals according to project requirements and Table 3-2.

5.Connectors P1 and P2 are removable to facilitate wiring termination. When reinstalling the connectors pay attention to the connector orientation. See Figures 3-2, 3-3, 3-4, 3-5, etc.
