Installation Precautions

The live wire and the neutral wire must pass through the core hole of the transformer at the same time;

Before the iron core is closed, ensure that the end face of the incision is clean, free of stains and impurities;

Use a torque wrench (electric/pneumatic) when tightening the screws, and set the torque to a reasonable range.
