Selecting the control cables

General rules
All control cables must be shielded.
Use a double-shielded twisted pair cable for analog signals. Employ one individually
shielded pair for each signal. Do not use common return for different analog signals.
A double-shielded cable is the best alternative for low-voltage digital signals but single-
shielded twisted pair cable (Figure b) is also usable.
Symmetrical shielded cable with three phase conductors and a concentric PE
conductor as shield. The shield must meet the requirements of IEC 61439-1, see
above. Check with local / state / country electrical codes for allowance.
Symmetrical shielded cable with three phase conductors and a concentric PE
conductor as shield. A separate PE conductor is required if the shield does not
meet the requirements of IEC 61439-1, see above.
Symmetrical shielded cable with three phase conductors and symmetrically
constructed PE conductor, and a shield. The PE conductor must meet the
requirements of IEC 61439-1.
A four-conductor system (three phase conductors and a protective conductor on a
cable tray).
WARNING! Ground all conductive cable supports, cable clamps and
individual conductive items close to cables, such as cable trays. A
dangerous voltage can become present on the non conductive outer
sheath of the cable. This can cause injury or death.
Symmetrical shielded cable with individual shields for each phase conductor is not
allowed on any power cabling.
