Wiring instructions
CD3000S unit has isolated heatsink. For safety connect the heatsink to earth using its terminal with earth
symbol.
CD3000S 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 lter and must be supplied with a dierent voltage
line.
• All input/output signals must use screened bilar wires.
• Signal input and output must not route in same cable try and must not be parallel.
• Local regulations regarding electrical installation should be rigidly observed
Use copper cables and wires rated for use at 75 °C only.
Use wire terminal UL Listed (ZMVV).
