2-10 Installing And Wiring Your Module
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. (Looking at 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 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. Ground one end only.
TB1
Connect ground wire to TB1
before installing module.
