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 92 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 96 Power Supply Wiring)
3.
Perform class D grounding (grounding resistance: 100  or less) for the ground [
Connect the grounded wire to the terminal. (Page 95 Grounding)
4.
Wire the input [X] terminal.
Select sink or source in the following wiring.
In the case of AC power supply type
