How to properly separate signal and power cables for RTU terminals EC32/EC60?

Signal and power cable separation for RTU terminals is essential for preventing electromagnetic interference and ensuring stable data transmission. The wiring requirements for EC32/EC60 series RTU terminals include:

• Physical separation: Signal and power cables should be routed separately with parallel distance ≥30cm, crossing at right angles when necessary
• Shielding measures: Use shielded twisted pair cables for 4-20mA signals and RS485 communication, with shield grounded at single point
• Layered wiring: Adopt upper-lower layered wiring in control cabinet, power cables on lower layer, signal cables on upper layer
• Ground isolation: Separate analog and digital signal grounds, connecting at single point finally

For solar power supply systems, DC24V power cables should use dedicated power cables, maintaining sufficient distance from 4G communication module antenna feeders. Radar flowmeter HZ-KSLF and other high-frequency equipment signal cables require strict shielding to prevent interference with RTU data acquisition, ensuring reliability of the entire monitoring system.
