1. Use the type of sensor selected on the Input Type Switch.
2. Do not connect anything to the N.C. terminals. (The N.C. terminals cannot
even be used as junction terminals.)
3. Do not connect any Current Transformer to the CT input terminals other
than an OMRON E54-CT1 or E54-CT3.
4. Always attach crimp terminals to the wiring that connects to the terminal
block and tighten the terminal screws securely. The terminal screws are
M3 screws and need to be tightened to a torque of 0.5 N ⋅ m.
5. Use wire that is AWG 22 to AWG 18.

Fork terminal
6.0 mm max.
6. Observe the following precautions when wiring to minimize noise and op-
timize the Temperature Control Unit's operation.
• Use twisted-pair shielded wire for the output wiring.
• Keep the I/O lines away from power lines including AC power supply
lines and high-power lines. Do not run the I/O lines in the same duct or
conduit as power lines.
