If the installation is not in hazardous area (safety barriers are not used):
The cable should be a simple cable used for power purposes, for example 3 times 1 or 1.5
mm².
Do not use a communication cable with twisted wires or a coaxial type.
If the installation is in hazardous area (safety barriers are used):
Use a cable of 3 conductors (gauge as described above), non-twisted inside outer jacket
(communication cables are not good).
The jacket should withstand 500 V RMS.
The capacitance between each two wires should not exceed 200 pF/meter.
The inductance of each wire should not exceed 0.7 uH/meter.
Select such a cable from a catalog or test its capacitance and inductance.
A shielded cable is not required in most cases.
Zener Safety Barriers for installation in hazardous area:
Note: MTL 715+ and 710+ are obsolete. Use MTL 7715+ and 7710+.
