4. Installation and Wiring
4.3 Wiring terminals
The terminal screw size of the T1-16S is M3. Use crimp-style terminals of 7mm width
or less useable for M3. The terminal block is not removable (fixed).
For input and output signal connections, refer to sections 2.4 and 3.

(1) NC stands for ”no connect”. Do not use the NC terminals for wire
relaying or branching.
(2) For the connections of the RS-485 communication port (the upper
terminal block), refer to the separate manual “T1-16S User’s Manual -
Communication Function -.

! CAUTION
1. Turn off power before wiring to minimize the risk of electrical shock.
2. Exposed conductive parts of wire can cause electrical shock. Use
crimp-style terminals with insulating sheath or insulating tape to cover
the conductive parts. Also close the terminal covers securely on the
terminal blocks when wiring has been completed.
3. Turn off power before removing or replacing units, modules, terminal
blocks or wires. Failure to do so can cause electrical shock or damage
to the T1-16S and related equipment.
