Wiring
Section 3-2
3-2-2
Wiring the Power Supply and I/O Lines
Wire Sizes
Use the following wires to connect external I/O devices to the NE1A-series
Controller.
Recommended Materials and Tools
■
Insulated Pin Terminals
Use a pin terminal with an insulated cover compliant with the DIN 46228-4
standard. Pin terminals similar in appearance but not compliant with the stan-
dard may not match the terminal block on the NE1A-series Controller. (The
wiring dimensions are rough standards. Confirm the dimensions beforehand.)
Use wires of the same diameter if two-wire pin terminals are used.
Note
• When wiring with pin terminals, be sure to insert pin terminals all the way
into the terminal block.
•
When using two-wire pin terminals, use wires of the same diameter.
•
When using two-wire pin terminals, insert the pin terminal so that metal
portion of the pin terminal is inserted straight into the terminal block, i.e.,
so that the long sides of the insulating cover are vertical.
Solid wire
0.2 to 2.5 mm
2
(AWG 24 to AWG 12)
Stranded (flexible) wire
0.34 to 1.5 mm
2
(AWG 22 to AWG 16)
Stranded wires should be prepared by attaching ferrules with plastic
insulation collars (DIN 46228-4 standard compatible) before con-
necting them.
