EMI Filter Wiring Diagram for Engraving Machine (3-Phase, 3-Wire System)

Terminal Identification:

Input Side (Power Supply):L1, L2, L3

Output Side (To Engraving Machine):L1', L2', L3'

Grounding: The chassis grounding terminal (usually marked with the earth symbol ⏚ or PE).

Connection Steps:

Power Input: Connect the three-phase power wires (L1, L2, L3) from your power supply to the corresponding L1, L2, L3 terminals on the filter's INPUT side.

Machine Output: Connect the wires going to your engraving machine to the L1', L2', L3' terminals on the filter's OUTPUT side.

Safety Ground:This is crucial! Connect a heavy-gauge ground wire from the power supply's earth point to the filter's dedicated grounding terminal on its metal chassis. Also, ensure the engraving machine itself is properly grounded.

⚠️ Important Warning:

DO NOT reverse the Input and Output connections. Incorrect wiring will severely degrade the filter's performance and may pose a safety risk.

Ensure all connections are tight and secure before powering on the system.
