Wiring Preparations
Wiring procedure
Before wiring, make sure that the source power supply is off.
1.
Prepare the parts for wiring.
Prepare crimp terminals and cables needed for wiring. (Page 107 Cable Connecting Procedure)
2.
Wire the power supply terminals.
For AC power supply type, connect the cables to the power [L] and [N] terminals.
For DC power supply type, connect the cables to the power [+] and [-] terminals.
Provide the protection circuit described in this chapter for the power supply circuit. (Page 114 Power Supply Wiring)
3.
Perform class D grounding (grounding resistance: 100 Ω or less) for the ground [
Connect the grounded wire to the terminal. (Page 113 Grounding)
4.
Wire the input [X] terminal.
Select sink or source in the following wiring.
In the case of AC power supply type
• For sink input, connect [24V][S/S] terminal
• For source input, connect [0V][S/S] terminal
In the case of DC power supply type
• For sink input, connect [+][S/S] terminal
• For source input, connect [-][S/S] terminal
Connect sensors and switches to the terminals. (Page 122 Input Wiring)
5.
Wire the output [Y] terminal.
Connect the load to terminals. (Page 134 Output Wiring)
6.
Wire built-in analog I/O terminal blocks.
Connect analog I/Os to terminals. (Page 149 Analog Wiring)
7.
Wire the built-in RS-485 communication terminal blocks and Ethernet communication connectors.
