Chapter 5 Typical Wiring
5.1 Voltage and Current Wiring Instruction
A. Three-phase Four-wire Wiring Mode (3LN, 3CT)
The star-like 3-Phase 4-Line wiring mode is commonly used in low-voltage electric distribution power
systems. The “UL” (voltage wiring mode) on the parameter setting interface should be set as “3Ln”;
“IL” (current wiring mode) should be set as “3C”.
B. Three-Phase Three-Line Wiring Mode (2LL, 2CT)
