Connection Capacity: 250 VAC 6A / 30 VDC 3A. Power Consumption: ≤ 10 VA. Installation: Standard DIN rail mounting (Plug-and-play design). 2. Core Protection Functions This device monitors the three-phase power supply for four critical fault conditions: Phase Sequence (Rotation): Ensures the motor rotates in the correct direction. Phase Loss (Failure): Detects if one of the three phases is missing. Overvoltage: Protects against surges that could burn out motor windings. Undervoltage: Prevents damage caused by low voltage which increases heat and current draw. 3. Basic Wiring & Operation While you should always consult the specific physical manual included with your unit, general wiring follows this pattern: L1, L2, L3: Connect these terminals to the three incoming power phases. Relay Contacts: The NO/NC contacts are typically wired into the control circuit of your motor's magnetic contactor. If a fault is detected (e.g., phases are swapped), the relay will trip, opening the contactor and stopping the motor. Status Indicators: LED lights on the faceplate usually indicate "Power" (Green) and "Fault" (Red). 4. Troubleshooting Common Faults Fault Light on Startup: This usually indicates the phase sequence is incorrect. Power down and swap any two of the three input wires (L1/L2/L3) to correct the rotation. Relay Not Engaging: Check for undervoltage or a missing phase using a multimeter.
