Ethernet Cable Specifications and Installation Rules

CommScope cable that meets Category 5e specifications can be purchased from Emerson or directly from the manufacturer (CommScope). CommScope type 5ES4 cable meets the minimum requirements for Category 5e cable used in 100Mbit and 1000Mbit Ethernet networks for DeltaV systems. Visit the CommScope web site for the most current specifications for Category 5e Screened 4 Twisted Pair Cable (ScTP).

In addition to CommScope cable, several types of Belden cable can be used as long as it meets or exceeds the CommScope 5ES4 category 5e performance and shielding specifications. Belden cable can be purchased through Belden cable distributors. If Belden cable is used, the basic cable installation and temperature specifications differ from the specifications shown in the following list.

Follow these rules when installing CommScope cable to protect the electrical performance of the cables:

• A cable is under loaded conditions when it is being pulled or it is under pressure. Under loaded conditions do not exceed:
  • 25 pounds pulling tension
  • 16 times the Outside Diameter (OD) of the cable (3.2 inches) for the minimum bend radius while pulling the cable
• A cable is under no load or unloaded conditions when the cable is being placed with no tension. Under unloaded conditions do not exceed:
  • 8 times the OD of the cable (1.6 inches) for the minimum bend radius
• Under both loaded and unloaded conditions, do not:
  • Install the cable unless the temperature is between 0°C and 60°C
  • Operate cable in environments outside the operating temperature range of -20°C and 60°C
