Section 3 Fixed-Mounted Circuit Breaker Installation Masterpact NW IEC Low-Voltage Power Circuit Breaker Installation Communicating Shunt Trip (MX) and Shunt Close (XF) recommended wiring schematic for the communicating style shunt trip or shunt close coils is shown in Figure 26. Induced voltages in the circuit at terminal C2 and/or 2 can cause the shunt trip or shunt close to not work properly. The best way to prevent the induced voltages is keep the circuit to terminal C2 and 2 as short as possible. If it is impossible to keep the circuit less than ten feet (three meters), use an interposing relay near terminal C2 or 2. ENGLISH Figure 26 Communicating Wiring Schematic Operating Order 10 ft.
