Note: The RS485 card is factory
installed, it does not need to be
re-installed.
Note: Use a twisted-pair, shielded
cable. Use of non-shielded cable
may result in radio frequency
emission or susceptibility levels
higher than allowed.
6. Tighten the connectors using a small flat-head screwdriver. Firmly tug on
each wire to ensure solid connections.
7. Reinstall the shielding plate and front cover if all of the wiring is complete.

This transmitter is designed for either a 4–20 or 0–20 mA output with a maximum
800 ohm load. Make output connections with twisted-pair shielded wire. Connect
the shield at the recorder or controlled component end only. On the opposite end,
remove the shield and insulate the remaining wires.
1. Remotely disconnect all instrument power before opening the analyzer door.
2. Remove the front cover.
3. Strip the insulation on the outer jacket back 7 inches. Remove the conductors
from the shield.
4. Cut the shield to 1 inch. Connect it to the ground on the shielding plate.
5. Strip the insulation on the remaining wires back ¼-inch.
6. Route the wire through the front left conduit opening. Use the provided
cord-connected strain reliefs to ensure adequate sealing. Use appropriate
NEMA sealing hardware.
7. Insert the wire ends into the Analog or RS485 connector until the insulation
seats against the connector. Refer to
