2. Installation

2.1 Hazardous Locations Installation 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 11 Approvals Label

2. For Ex d installations, ensure that the sensor is properly threaded into a suitable explosion-proof rated

junction box with a downward pointing female ¾” NPT threaded connection. The sensor should be

threaded up at least 5 full turns until tight, with the LED display facing forward. Avoid use of Teflon

Tape, or any type of non-conductive pipe thread coating on the NPT threaded connection.

3. A good ground connection should be verified between the sensor’s metal enclosure and the junction

box. If a good ground connection is not made, the sensor can be grounded to the junction box using

the sensor’s external ground lug. Also verify a good ground connection between the junction box and

earth ground.

4. 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 Splash Guard.

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

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

7. These sensors meet ATEX standards EN60079-0, EN60079-18 and EN60079-11.

8. These sensors pass dielectric strength of 500VRMS between circuit and enclosure for a minimum of 1

minute at a maximum test current of 5mA.

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
