Wiring Power Supply and Ground Lines
CPU Units with DC Power Supply
DC Power Supply Wiring
• Use crimp terminals or solid wire for wiring the power supply. Do not con-
nect bare stranded wires directly to terminals.
• M3 self-rising terminal screws are used. Tighten the terminal screws to
the torque of 0.5 N·m.
• To prevent noise, use a ground line of 100
Ω
or less.
• Provide a power supply of 20.4 to 26.4 VDC.
• The maximum current consumption is 20 W for CPU Units with 30 or 40
I/O points and 13 W for CPU Units with 20 I/O points.
• When the power supply is turned ON, the inrush current is approximately
five times the normal current.
• The GR terminal is a ground terminal. To prevent electrical shock, use a
dedicated ground line (2 mm
2
min.) of 100
Ω
or less.
Note
(1) Never reverse the positive and negative leads when wiring the power sup-
ply terminals.
(2) Supply all power to the power supply terminals from the same source.
