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 module or the power
supply return (0V). Do not ground the shield at both the module and the
transducer.
S
Do not 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 F4–04DA requires a separate power supply. The DL430/440/450 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. Depending on the number of
modules and types of output signals used, you can use this power source instead of
a separate supply. If you would rather use a separate supply, choose one that
meets the following requirements: 21.6–26.4 VDC, Class 2, 500mA current. If you
are using current loops, add 20 mA per current loop.
