Wiring
Section 3-2
• When wiring a Unit, leave the protective label on the top of the Unit in
place to prevent wire clippings or other materials from getting inside the
Unit. When the wiring has been completed, the label must be removed to
allow air to flow for cooling.

Wiring
Terminal Arrangement
The following diagram shows the signal names associated with the connect-
ing terminals.
The Universal Input Units have 4 input channels on each Unit, and the type of
input connected to each channel can be set independently.
Wiring Analog Inputs
Ground the shield of the shielded cable to protect against the affects of noise.
Note
1.
Be sure to wire the correct terminals when wiring voltage inputs. The Unit
may fail if a voltage input is wired incorrectly.
2.
Do not connect anything to terminals that are not being used.
3.
Do not connect anything to NC terminals. Do not use NC terminals as relay
terminals.
