Good Wiring Practices
To reduce interference and improve signal quality, use the following practices
for all communication wiring:
• Keep shielding on the cable as close to the terminal as possible.
• Do not untwist pairs more than necessary.
• Do not allow cable strands to fray.
• Do not tin cable leads with solder.
• Fold un-insulated wire over onto itself before inserting into a terminal.
• Make sure screw terminals are tight.
A minimal, typical arrangement of the components is shown in Figure 8:
