Installation Instructions
32-Channel Analog Input Module
Quantum Series 140 AxI 05x 00sc

Before installing the module, you should:

•

Configure all of the appropriate zoom screen, configuration and
other necessary set up according to Chapters 2 and 3.

•

Field wire the module’s terminal block for your application.

For field wiring, use shielded, twisted-pair cable (such as Belden 9418 for
voltage and current applications), and ground each cable’s shield wire at
one end only. At the opposite end of each cable, tape the exposed shield
wire to insulate it from electrical contact. A good shield wire ground is a
rack assembly mounting bolt or stud.

Field Wiring

+ Note: In the process of wiring the modules, route all signal wires as far as possible from potential

sources of electrical noise, such as motors, transformers, etc., (especially ac devices). As
a general rule, allow 15.2 cm (6 in) of separation for every 120V of power. Signal wires
must never share the same conduit with ac wiring. Also, when you must route signal wires
past ac wiring, do so at right angles.
