Access Requirements When choosing a mounting location and position, take into account the need
for access to the transmitter.
Make wiring terminations through the conduit openings at the top of the
electronics housing. The field terminal side of the transmitter is clearly marked
on the transmitter neck. Test terminals are incorporated on the terminal block;
you do not need access to the electronics compartment to perform calibration
procedures.
The transmitter electronics compartment contains the electronics module with
failure mode and security jumpers, and the optional LCD meter. Consider the
need for access to both compartments when installing the transmitter. Refer
to Figure 3-5 for transmitter dimensional drawings.
