Installation of a B12 Transmitter requires mechanically mounting the enclosure and connecting
DC power to the system. In addition, the sensor must be installed as shown in either figures 1 or 2 and
wired to the proper terminals in the transmitter.
MECHANICAL MOUNTING
The NEMA 4X transmitter enclosure is surface mounted using screws inserted through the blind
mounting holes accessible by removing the transmitter cover. Figure 3 shows the center to center
mounting hole dimensions for this enclosure. If rigid conduit is to be used for wiring the transmitter, the
transmitter can be supported directly from the conduit system without the use of mounting screws. The
transmitter weighs only 4 ounces, so normal conduit supports will be adequate. If conduit is to be used,
be sure that the conduit is sealed at the point were it enters the transmitter. Otherwise, condensation in
the conduit system can drain into the transmitter causing failure of the electronic circuit board.
CAUTION: When removing the cover of a transmitter with the LCD option, do not try to separate the
cover from the enclosure base by more than a few inches. The LCD is hardwired to the transmitter circuit
board, and the display cable is only a few inches long.
