Requirements
Your company may have guidelines for wiring and cable installation. If so, you
should check those before you begin the installation. Here are some general things
to consider.
S
Use the shortest wiring route whenever possible.
S
Use shielded wiring and ground the shield at the transmitter source. Do
not ground the shield at both the module and the source.
S
Don't run the signal wiring next to large motors, high current switches,
or transformers. This may cause noise problems.
S
Route the wiring through an approved cable housing to minimize the
risk of accidental damage. Check local and national codes to choose
the correct method for your application.
The F4–16AD–2 module requires a separate power supply. The Series DL405
CPUs, D4-RS Remote I/O Controller, and D4-EX Expansion Units have built-in 24
VDC power supplies that provide up to 400mA of current. If you only have a couple
analog modules, you can use this power source instead of a separate supply. If you
have more than four analog modules, or you would rather use a separate supply,
choose one that meets the following requirements: 24 VDC $10%, Class 2, 100
mA current (per module).
