Network Design and Setup

Your company may have guidelines for cable installation. If so, you should check

those before you begin the installation. Here are some general things to consider.

S Don’t run cable next to larger motors, high current switches, or

transformers. This may cause noise problems.

S Route the cable through an approved cable housing to minimize the risk

of accidental cable damage. Check local and national codes to choose

the correct method for your application.

S Consider redundant cabling if the application data is critical. This allows

you to quickly reconnect all stations while the primary cable is being

repaired.

Cable Shield Grounding — No matter what type of configuration is required, it is

important to ground the cable shield to minimize the possibility of noise. The

preferred method is to connect one end (preferably the receiver end) of the cable

shield to the connector housing. If noise problems are still present and you have a

good earth ground for the cabinet, you should connect one end of the shield to the

cabinet earth ground. Don’t ground both ends of the shield because this will create

induced noise on the cable.

Step 2: Crimp a ring connector onto the shield.
