Notice to Customers

Dear Valued Customer,

To ensure reliable operation and maximize the service life of our contactors, please ensure all coil control wiring connections are secure during installation or testing. Loose terminal connections may cause electrical arcing, leading to contactor damage and potential equipment failure.

We strongly recommend:

1. Carefully reviewing the circuit diagram prior to wiring.

2. Following specified wiring procedures.

3. Verifying that all coil terminal screws are properly tightened.

4. Confirming that no foreign objects are present near the terminals.
