2. Installation

2.1 Operational Guidelines for Safe Use

1. Install sensor only in areas with classifications matching with those described on the approval label.

Follow all warnings listed on the label.

2. Ensure that the sensor is properly mounted in a vertical orientation with sensor facing down. Avoid

use of excessive Teflon Tape, or any type of non-conductive pipe thread coating on the NPT threaded

connection. All NPT connections should remain grounded to the junction box.

3. Use ¾” NPT plugs properly rated for hazardous locations to block any unused connections.

4. Removal of the Junction box cover or High Temperature senor violates the Ex Proof protection

method and hence power must be removed from the sensor prior to its safe removal.

5. Proper precautions should be taken during installation and maintenance to avoid the build-up of static

charge on the plastic components of the sensor. These include the splashguard and splashguard

adapter.

6. Do not operate the sensor outside of the stated operating temperature limits.

7. Do not operate the sensor outside the stated operating limits for voltage supply.

2.2 Sensor Placement

Selection of sensor location is critical to the overall safe performance of the product. Six factors play an

important role in selection of sensor locations:

(1) Density of the gas to be detected

(2) Most probable leak sources within the industrial process

(3) Ventilation or prevailing wind conditions

(4) Personnel exposure

(5) Maintenance access

(6) Additional Placement Considerations
