1.1 Installation checklist
Make sure that the hazardous area specified on the approval tag is suitable for the
environment in which the meter will be installed.
Verify that the local ambient and process temperatures are within the limits of the
meter.
If your sensor has an integral transmitter, no wiring is required between the sensor and
transmitter. Follow the wiring instructions in the transmitter installation manual for
signal and power wiring.
If your transmitter has remote-mounted electronics, follow the instructions in this
manual for wiring between the sensor and the transmitter, and then follow the
instructions in the transmitter installation manual for power and signal wiring.
