2. Installation
2.1 ATEX 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.
Figure 6 TP 624D ATEX Approval Labels
2. Ensure that the sensor is properly mounted in a vertical orientation with sensor facing down. Avoid
use of Teflon Tape, or any type of non-conductive pipe thread coating on the NPT threaded
connection.
3. Use ¾” NPT plugs properly rated for hazardous locations to block any unused connections
4. Removal of the Junction box cover or threaded sensor housing (399-800000-000) violates the Ex d
protection method and hence power must be removed from the sensor prior 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.
8. These sensors meet EN60079-0, EN60079-1.
2.2 Sensor Placement
Selection of sensor location is critical to the overall safe performance of the product. Five 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
