The Model 154XST has provisions for mounting to 3/4" pipe and may be mounted in any
position. Before mounting, ensure that mating threads are clean. To prevent the ingress of water
and dust, apply conductive sealant to the conduit threads prior to mounting. If non-conductive
sealant is used, the enclosure must be earthed via the provided internal grounding wire/ground-
ing screw to ensure proper grounding continuity. In high-humidity environments when units are
