4.3 Recommended Cable Types
The following section lists recommended cable types for both the DDA power supply circuit and the DDA communication circuit.
The lists are not inclusive of all cable types and cable manufacturers and should serve only as a guideline when choosing
cables. Other cable types can be selected that meet the requirements of the DDA system.
Recommended cable types for the DDA power supply circuit (individual cable pair):
General requirements:
• shielded, twisted pair
• 24 picofarads/foot or less. See note below.
• minimum 0.010 in. (0.25 mm) insulation thickness
NOTE:
For the power supply circuit, the return conductor is
connected to the shield at the safety barrier ground
terminal. When determining the capacitance of cable
for the power supply circuit, use the manufacturer’s
capacitance specifications shown for one conductor
and the other conductor connected to the shield.
