Current output wiring
Emerson ships all instruments with two 4-20 mA current outputs. Wiring
locations for the outputs are on the main board which is mounted on the
hinged door of the instrument.
Wire the output leads to the correct position on the main board using the
lead markings (+/positive, -/negative) on the board. Emerson provides male
mating connectors with each unit.
For best EMI/RFI protection use shielded output signal cable enclosed in an
earth-grounded metal conduit. Connect the shield to earth ground. AC
wiring should be 14 gauge or greater. Provide a switch or breaker to
disconnect the analyzer from the main power supply. Install the switch or
breaker near the analyzer and label it as the disconnecting device for the
analyzer.
Keep sensor and output signal wiring separate from power wiring. Do not
run sensor and power wiring in the same conduit or together in a cable tray.
