4. Installation and Wiring

4.3 Wiring terminals

! 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.

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).

NOTE

For input and output signal connections, refer to sections 2.4 and 3.

NOTE

(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 -.

The applicable wire size is 0.3mm2 (22 AWG) to 1.25mm2 (16 AWG). The table below shows the recommended wire size.
