• Do not touch or remove the cold-junction compensator.
• Use the type of sensor selected on the Input Type Switch.
• The Temperature Control Unit and Terminal Block are a matched set, so
use the Temperature Control Unit and Terminal Block with matching serial
numbers.
• Do not connect anything to the N.C. terminals. (The N.C. terminals cannot
even be used as junction terminals.)
• Do not connect any Current Transformer to the CT input terminals other
than an OMRON E54-CT1 or E54-CT3.
