Note 1: Use cables specifically designed for use with thermocouple temperature sensor J-type,
K-type, R-type, S-type, T-type, E-type and N-type, or use double shielded cables to
minimize the effects of noise. Temperature inputs should be separated from power cable
or other wiring that may cause interference.
Note 2: Connect the
terminal on both power supply and the ELCM-TC04ANNN to a
proper system ground.

Note: Use 12-28 AWG single-core bare wire or multi-core (stranded) wire for the I/O wiring.
The ELCM terminal screws should be tightened to 4.75 kg-cm (4.12 in-lbs) and please
use 60/75°C copper conductor only.
