CD3000M can be susceptible to airborne interferences from near equipment or from interferences
on main supply, so a number of precautions must be taken.
• Contactors coils and chokes must have in parallel a RC filter and must be supplied with a
different voltage line.
• All input/output signal must use screened bifilar wires.
• Signal input and output must not routing in same cable try and must not be parallel.
• Local regulations regarding electrical installation should be rigidly observed.
