2.8 Installation Verification
2.8.1 Network Cabling Installation Verification
After installation is complete and prior to operation, inspect the network cable and its connection to
each field device.
NOTE: Units should be disconnected from power. The network should be disconnected from the host
device.
Check for the following:
1. There should not be:
• Nicks in the insulation - this can cause a short to the grounded shield.
• Cut strands in a stranded conductor - this can cause a poor connection and eventually an open
circuit.
2. Cable armor shorted to the cable shield/drain wire this may not be at ground potential and could
be subject to lightning surges.
3. The Shield/drain wire should only be grounded at one point in the segment to avoid ground loop
problems.
4. The ground/earth connection should be at true ground potential and effective at all times. See No.
5 in Section 2.6.1, Site Preparation.
