z Crimp Terminals
The terminals on the Power Supply Unit are M4, self-raising terminals with screws.
Precautions for Correct UsePrecautions for Correct Use
• Use crimp terminals for wiring.
• Do not connect bare stranded wires directly to terminals.
• Tighten the terminal block screws to the torque of 1.2 N·m.
• Use crimp terminals (M4) having the dimensions shown below.
z Crimp Terminals for DC Power Supply
An alarm output is provided on Power Supply Units with a replacement notification function. Connect
the alarm output to a PLC's Input Unit or external LED indicator to enable notification when Power Sup-
ply Unit replacement is required.
