2. Installation
2.1 Hazardous Locations Installation Guidelines for Safe Use
1. Install the sensor only in areas with classifications matching the approval label. Follow all warnings
listed on the label.
Figure 6 Approval Label
2. Do not remove the junction box cover while in the classified are unless it is conformed the there is no
explosive gas levels in the area.
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. Verify a good ground connection between the junction box and earth
ground.
4. Proper precautions should be taken during installing and maintenance to avoid the build-up of static
charge on the plastic components of the sensor (Splash Guard) Wipe with damp cloth on plastic
components to avoid static discharge.
5. Do not substitute components. Substitution of components may impair the intrinsic safety rating.
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 ATEX standards EN60079-0:2012. EN60079-1:2007 and EN60079-11:2012.
9. These sensors have a maximum safe location voltage of Um=30V.
10. The CX-DM apparatus is not capable of withstanding the 500V insulation test required by clause
6.3.12 of IEC/EN 60079-11:2007 (and by clause 6.8.1 of CSA Std. 142); thus, the enclosure must be
grounded.
