process. A cover on the front of the junction box allows access to the interior of the
junction box.
Installation
This section describes procedures to mount the combustible gas detector in the
monitoring environment and wire the detector to a controller.
NOTE: The 61-0140RK-05 detector retains its explosion proof classification only when
installed in the explosion proof junction box. The detector is not explosion proof
if installed in a controller conduit hub.
Mounting the Combustible Gas Detector
1. Select a mounting site that is representative of the monitoring environment. Consider
the following when you select the mounting site.
• Select a site where the detector is not likely to be bumped or disturbed. Make sure
there is sufficient room to perform start-up, maintenance, and calibration
procedures.
• Select a site where the target gas is likely to be found first. For lighter gases,
mount the detector near the ceiling; for heavier gases, mount the detector near the
floor.
