Wiring to I/O and NC-bus terminals
The I/O and NC-bus wires are connected to the screwless push-in terminals of Infilex AC. Follow the procedure below for the I/O
and NC-bus wiring.
1) Strip the wire sheath 8 mm.
Note:
* Scale for the strip length is indicated on the front surface of Infilex AC basic unit. If the insulation stripped part is longer than 8 mm, it
may get exposed, causing electrical shock or short circuit between adjacent terminals. If it is shorter, it may not contact the terminal
connector.
2) Make sure that no wire fiber goes out of the wire end.
3) Press the button on the terminal block deeply enough using a slotted screwdriver and insert the wire.
(Maximum button-pressing force is 23 N.)
Then, release the button.
4) Gently pull out the wire horizontally to make sure that it is completely held by the clamp and check no wire fiber being
disconnected from the terminal.
Note:
* If you pull out the wire diagonally, it may be disconnected.
Arrangement of the wires connected to Infilex AC
Notes:
* Neatly place the wires using cable ties or the like so as not to hide LED, Data Setter connector,

mark of Data Setter connector, S1 switch,
battery holder, and indication tag.
* Do not leave slack in the wires that run between the cable duct and Infilex AC.
* Sideway mounting shown in the figure above is allowed only when I/O module, UT module, or integral type Operator Panel is NOT
assembled with the basic unit. Do not mount the Infilex AC basic unit sideway with the power supply terminals located upper corner, lying on
its back, or lying face down.
Always install the basic unit assembled with an I/O module, and/or UT module/integral type Operator Panel in upright position.
