Publication 1746-5.23
6. Connect the signal wires of each channel to the terminal block.
7. Connect TB1 chassis ground connector to the nearest chassis mounting bolt
with 14 gauge wire. (On the face of the module, TB1 is near the lower part
of the terminal block on the primary side of the PCB.)
8. At the sensor-end of cables from thermocouple/mV devices:
• remove the drain wire and foil shield
• apply shrink wrap as an option
• connect to thermocouple/mV devices keeping the leads short
Important:
Only after verifying that your connections are correct for each
channel, trim the lengths to keep them short. Avoid cutting
leads too short.
Important:
If noise persists, try grounding the opposite end of the cable
instead. (Ground one end only.)
