Wiring Methods
2. Do not connect bare stranded wires directly to terminals.
• Confirm that the Units have been mounted properly.
• Do not remove the protective label from the top of the Unit until wiring has
been completed. This label prevents wire strands and other foreign matter
from entering the Unit during wiring procedures.
• Remove the label after wiring has been completed to allow air circulation
needed for cooling.
During wiring
• Wire the Units so that they can be easily replaced.
• In addition, make sure that the I/O indicators are not covered by the wir-
ing.
• Do not place the wiring for I/O Units in the same duct or raceway as power
lines. Inductive noise can cause errors in operation.
• Tighten the terminal screws to the torque of 0.8 N m.
After wiring
Remove the label.
