2.0 Mounting and Wiring
Each sensor/transmitter circuit and sensor are in a NEMA-4 aluminum enclosure, which has a combination liquid and RFI O-ring
in the cover. When used with an appropriate liquid tight conduit fitting, the enclosure is sealed to the environment. The interior
of a typical S/T is shown in Figure 2.
When determining location of S/T here are 3 main factors to consider.
♦
Density of gas to be detected: high for gases lighter than air and low for gases heavier than air
♦
Leak point: determination of the probable source of a leak
♦
In the flow of air in ventilated rooms.
Mount the sensor/transmitter to an appropriate stable vertical surface with the sensor facing downward.
C AUTION : Since the sensor/transmitter detects gas only at the sensor location, pay attention to the possible sources of gas, the
density of the gas, locations where the gas may be confined and locations where the gas may damage or injure property or
personnel, when choosing locations of sensor/transmitters.
Mount the sensor/transmitter using the two mounting holes in the corners of the enclosure. For maximum RFI protection the
enclosure should be grounded to earth ground, either by means of the mounting screws, a conductive conduit, or a wire
connected to earth ground.
